Cisco has released Vulnerability-related.PatchVulnerability a new patch designed to fix Vulnerability-related.PatchVulnerability a failed update which has not prevented the exploit of a severe Webex vulnerability . The original security flaw , CVE-2018-15442 , is present in Vulnerability-related.DiscoverVulnerability the Cisco Webex Meetings Desktop App for Windows and is described Vulnerability-related.DiscoverVulnerability as a bug which `` could allow an authenticated , local attacker to execute arbitrary commands as a privileged user . '' Cisco 's original security update was published Vulnerability-related.PatchVulnerability in October in order to remedy Vulnerability-related.PatchVulnerability the flaw , in which a lack of validation for user-supplied parameters in the app could be harnessed to exploit the bug . If an attacker is successful in utilizing the vulnerability , they can force the app to run arbitrary commands with user privileges . `` While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access , administrators should be aware that in Active Directory deployments , the vulnerability could be exploited Vulnerability-related.DiscoverVulnerability remotely by leveraging the operating system remote management tools , '' the company added . Software releases prior to 33.6.4 -- alongside Cisco Webex Productivity Tools Releases 32.6.0 and later prior to 33.0.6 -- are impacted on Windows systems . It was not long after the release Vulnerability-related.PatchVulnerability of the first patch that researchers from SecureAuth deemed the original fix incomplete . The original patch only forced the service to run files signed by Webex , but failed to account for DLL-based attacks , according to the team . `` The vulnerability can be exploited Vulnerability-related.DiscoverVulnerability by copying to a local attacker controller folder , the ptUpdate.exe binary , '' the researchers said Vulnerability-related.DiscoverVulnerability in an advisory . `` Also , a malicious dll must be placed in the same folder , named wbxtrace.dll . To gain privileges , the attacker must start the service with the command line : sc start webexservice install software-update 1 `` attacker-controlled-path '' ( if the parameter 1 does n't work , then 2 should be used ) . '' These findings were sent to Cisco , which acknowledged the DLL attack method . A new patch was then issued Vulnerability-related.PatchVulnerability roughly a week after being informed Vulnerability-related.DiscoverVulnerability of the issue . `` After an additional attack method was reported to Cisco , the previous fix for this vulnerability was determined to be insufficient , '' Cisco says . `` A new fix was developed Vulnerability-related.PatchVulnerability , and the advisory was updated Vulnerability-related.PatchVulnerability on November 27 , 2018 , to reflect which software releases Vulnerability-related.PatchVulnerability include the complete fix .

Adobe has patched Vulnerability-related.PatchVulnerability two critical flaws in Acrobat and Reader that warrant urgent attention . Officially , Adobe patches Vulnerability-related.PatchVulnerability security vulnerabilities around the middle of each month to coordinate with Microsoft ’ s Patch Tuesday , but recently it ’ s become almost routine for the company to issue Vulnerability-related.PatchVulnerability out-of-band updates in between . APSB19-02 , the first of such updates to reach customers in the new year , addresses Vulnerability-related.PatchVulnerability critical flaws with a priority rating of ‘ 2 ’ . That means that the flaw is potentially serious , but Adobe hasn ’ t detected Vulnerability-related.DiscoverVulnerability any real-world exploits ( the latter would entail issuing Vulnerability-related.PatchVulnerability an ‘ emergency ’ patch with a ‘ 1 ’ rating ) . The first flaw , identified Vulnerability-related.DiscoverVulnerability as CVE-2018-16011 , is described Vulnerability-related.DiscoverVulnerability by Adobe as a use-after-free bug that could be exploited Vulnerability-related.DiscoverVulnerability using a maliciously crafted PDF to take control of a target system with their malware of choice .

As critical flaws with a ‘ 2 ’ rating , there is a suggested 30-day window within which to apply Vulnerability-related.PatchVulnerability the updates , but it ’ s worth bearing in mind that a new round of patches will likely be offered Vulnerability-related.PatchVulnerability for Adobe products tomorrow as part of Patch Tuesday . In December ’ s Patch Tuesday , Adobe released Vulnerability-related.PatchVulnerability a not inconsiderable 87 patches , including 39 rated critical . Only days before , Adobe issued Vulnerability-related.PatchVulnerability an emergency Flash patch for a zero-day vulnerability that was being exploited Vulnerability-related.DiscoverVulnerability , while in November Flash received Vulnerability-related.PatchVulnerability a separate patch for one whose exploitation was believed to be imminent .
