Thousands , if not more , Jenkins servers are vulnerable Vulnerability-related.DiscoverVulnerability to data theft , takeover , and cryptocurrency mining attacks . This is because hackers can exploit two vulnerabilities to gain admin rights or log in using invalid credentials on these servers . Both vulnerabilities were discovered Vulnerability-related.DiscoverVulnerability by security researchers from CyberArk , were privately reported Vulnerability-related.DiscoverVulnerability to the Jenkins team , and received Vulnerability-related.PatchVulnerability fixes over the summer . But despite patches for both issues , there are still thousands of Jenkins servers available Vulnerability-related.PatchVulnerability online . Jenkins is a web application for continuous integration built in Java that allows development teams to run automated tests and commands on code repositories based on test results , and even automate the process of deploying new code to production servers . Jenkins is a popular component in many companies ' IT infrastructure and these servers are very popular with both freelancers and enterprises alike . Over the summer , CyberArk researchers discovered Vulnerability-related.DiscoverVulnerability a vulnerability ( tracked as Vulnerability-related.DiscoverVulnerability CVE-2018-1999001 ) that allows an attacker to provide malformed login credentials that cause Jenkins servers to move their config.xml file from the Jenkins home directory to another location . If an attacker can cause the Jenkins server to crash and restart , or if he waits for the server to restart on its own , the Jenkins server then boots in a default configuration that features no security . In this weakened setup , anyone can register on the Jenkins server and gain administrator access . With an administrator role in hand , an attacker can access private corporate source code , or even make code modifications to plant backdoors in a company 's apps . This lone issue would have been quite bad on its own , but CyberArk researchers also discovered Vulnerability-related.DiscoverVulnerability a second Jenkins vulnerability -- CVE-2018-1999043 . This second bug , they said Vulnerability-related.DiscoverVulnerability , allowed an attacker to create ephemeral user records in the server 's memory , allowing an attacker a short period when they could authenticate using ghost usernames and credentials . Both vulnerabilities were fixed Vulnerability-related.PatchVulnerability , the first in July and the second in August , but as we 've gotten accustomed to in the past few years of covering security flaws , not all server owners have bothered to install these security updates .

A vulnerability affects Vulnerability-related.DiscoverVulnerability all versions of the OpenSSH client released in the past two decades , ever since the application was released in 1999 . The security bug received Vulnerability-related.PatchVulnerability a patch this week , but since the OpenSSH client is embedded in a multitude of software applications and hardware devices , it will take months , if not years , for the fix to trickle down Vulnerability-related.PatchVulnerability to all affected systems . This particular bug was analyzed Vulnerability-related.DiscoverVulnerability last week by security researchers from Qualys who spotted Vulnerability-related.DiscoverVulnerability a commit in OpenBSD 's OpenSSH source code for a bug report submitted Vulnerability-related.DiscoverVulnerability by Darek Tytko from securitum.pl . After analyzing the commit , researchers realized that the code inadvertently fixed Vulnerability-related.PatchVulnerability a security bug lying dormant in the OpenSSH client since its creation . This bug allows a remote attacker to guess the usernames registered on an OpenSSH server . Since OpenSSH is used with a bunch of technologies ranging from cloud hosting servers to mandate IoT equipment , billions of devices are affected . As researchers explain , the attack scenario relies on an attacker trying to authenticate on an OpenSSH endpoint via a malformed authentication request ( for example , via a truncated packet ) . A vulnerable OpenSSH server would react in two very different ways when this happens . If the username included in the malformed authentication request does not exist , the server responds with authentication failure reply . If the user does exist , the server closes the connection without a reply . This small behavioral detail allows an attacker to guess valid usernames registered on a SSH server . Knowing the exact username may not pose an immediate danger , but it exposes that username to brute-force or dictionary attacks that can also guess its password . Because of OpenSSH 's huge install base , the bug is ideal for both attacks on high-value targets , but also in mass-exploitation scenarios . The bug — tracked as Vulnerability-related.DiscoverVulnerability CVE-2018-15473— has been patched Vulnerability-related.PatchVulnerability in the stable version of OpenSSH —1:6.7p1-1 and 1:7.7p1-1— and the 1:7.7p1-4 unstable branch . Patches have also trickled down Vulnerability-related.PatchVulnerability to Debian , and most likely other Linux distros .

A critical vulnerability in Kubernetes open-source system for handling containerized applications can enable an attacker to gain full administrator privileges on Kubernetes compute nodes . Kubernetes makes it easier to manage a container environment by organizing application containers into pods , nodes ( physical or virtual machines ) and clusters . Multiple nodes form a cluster , managed by a master that coordinates cluster-related activities like scaling , scheduling , or updating apps . Each node has an agent called Kubelet that facilitates communication with the Kubernetes master via the API . The number of nodes available in a Kubernetes system can be hundreds and even thousands . Pulling this off is easy on default configurations , where `` all users ( authenticated and unauthenticated ) are allowed to perform discovery API calls that allow this escalation , '' says Jordan Liggitt , staff software engineer at Google . The security bug was discovered Vulnerability-related.DiscoverVulnerability by Darren Shepherd , co-founder of Rancher Labs company that provides the Kubernetes-as-a-Service solution called Rancher . Now tracked as Vulnerability-related.DiscoverVulnerability CVE-2018-1002105 , the flaw is critical , with a Common Vulnerability Scoring System ( CVSS ) score of 9.8 out of 10 . According to the latest version of the vulnerability severity calculator , exploiting the security glitch has low difficulty and does not require user interaction . Red Hat 's OpenShift Container Platform uses Kubernetes for orchestrating and managing containers is also impacted Vulnerability-related.DiscoverVulnerability by the vulnerability . In an advisory on the matter , the company explains that the flaw can be used in two ways against its products . One involves a normal user with 'exec , ' 'attach , ' or 'portforward ' rights over a Kubernetes pod ( a group of one or more containers that share storage and network resources ) ; they can escalate their privileges to cluster-admin level and execute any process in a container . The second attack method exploits the API extension feature used by ‘ metrics-server ’ and ‘ servicecatalog ’ in OpenShift Container Platform , OpenShift Online , and Dedicated . No privileges are required and an unauthenticated user can get admin rights to any API extension deployed to the cluster . `` Cluster-admin access to ‘ servicecatalog ’ allows creation of service brokers in any namespace and on any node , '' the advisory details . The problem has been addressed Vulnerability-related.PatchVulnerability in the latest Kubernetes revisions : v1.10.11 , v1.11.5 , v1.12.3 , and v1.13.0-rc.1 . Kubernetes releases prior to these along with the products and services based on them are affected Vulnerability-related.DiscoverVulnerability by CVE-2018-1002105 . Red Hat released Vulnerability-related.PatchVulnerability patches for the OpenShift family of containerization software ( OpenShift Container Platform , OpenShift Online , and OpenShift Dedicated ) and users received Vulnerability-related.PatchVulnerability service updates they can install at their earliest convenience . The software company warns that a malicious actor could exploit the vulnerability to steal Attack.Databreach data or inject malicious code , as well as `` bring down production applications and services from within an organization ’ s firewall . ''

Security researchers at Qualys Security have discovered Vulnerability-related.DiscoverVulnerability a Linux flaw that could be exploited Vulnerability-related.DiscoverVulnerability to gain root privileges and overwrite any file on the filesystem on SELinux-enabled systems . The high severity flaw , tracked as Vulnerability-related.DiscoverVulnerability CVE-2017-1000367 , resides in Vulnerability-related.DiscoverVulnerability the Sudo ’ s get_process_ttyname ( ) for Linux and is related to the way Sudo parses tty information from the process status file in the proc filesystem . The Linux flaw could be exploited Vulnerability-related.DiscoverVulnerability by a local user with privileges to execute commands via Sudo and could allow attackers to escalate their privileges to root . The Sudo ’ s get_process_ttyname ( ) function opens “ /proc/ [ pid ] /stat ” ( man proc ) and reads the device number of the tty from field 7 ( tty_nr ) . These fields are space-separated , the field 2 ( comm , the filename of the command ) can contain spaces . Sudoer users on SELinux-enabled systems could escalate their privileges to overwrite any file on the filesystem with their command ’ s output , including root-owned files . “ We discovered Vulnerability-related.DiscoverVulnerability a vulnerability in Sudo ’ s get_process_ttyname ( ) for Linux : this function opens “ /proc/ [ pid ] /stat ” ( man proc ) and reads the device number of the tty from field 7 ( tty_nr ) . Unfortunately , these fields are space-separated and field 2 ( comm , the filename of the command ) can contain spaces ( CVE-2017-1000367 ) . ” reads the security advisory . “ On an SELinux-enabled system , if a user is Sudoer for a command that does not grant him full root privileges , he can overwrite any file on the filesystem ( including root-owned files ) with his command ’ s output , because relabel_tty ( ) ( in src/selinux.c ) calls open ( O_RDWR|O_NONBLOCK ) on his tty and dup2 ( ) s it to the command ’ s stdin , stdout , and stderr . This allows any Sudoer user to obtain full root privileges. ” To exploit the issue , a Sudo user would have to choose a device number that doesn ’ t exist under “ /dev ” . If the terminal isn ’ t present under the /dev/pts directory when the Sudo performs a breadth-first search of /dev , the user could allocate a pseudo-terminal between the two searchers and create a “ symbolic link to the newly-created device in a world-writable directory under /dev , such as /dev/shm , ” “ Exploiting the bug requires that the user already have sudo privileges . SELinux must also be enabled on the system and sudo must have been built with SELinux support . To exploit the bug , the user can choose a device number that does not currently exist under /dev . If sudo does not find the terminal under the /dev/pts directory , it performs a breadth-first search of /dev . It is possible to allocate a pseudo-terminal after sudo has checked /dev/pts but before sudo performs its breadth-first search of /dev . The attacker may then create a symbolic link to the newly-created device in a world-writable directory under /dev , such as /dev/shm. ” read a Sudo alert . “ This file will be used as the command ’ s standard input , output and error when an SELinux role is specified on the sudo command line . If the symbolic link under /dev/shm is replaced with a link to an another file before it is opened by sudo , it is possible to overwrite an arbitrary file by writing to the standard output or standard error . This can be escalated to full root access by rewriting a trusted file such as /etc/shadow or even /etc/sudoers. ” The Linux flaw affects Vulnerability-related.DiscoverVulnerability all Sudo versions from 1.8.6p7 through 1.8.20 , the Sudo 1.8.20p1 fixes Vulnerability-related.PatchVulnerability it , the issue was rated with a CVSS3 Base Score of 7.8 .
