CWE-276

An issue was discovered in SolarWinds MSP PME (Patch Management Engine) Cache Service before 1.1.15 in the Advanced Monitoring Agent. There are insecure file permissions for %PROGRAMDATA%SolarWinds MSPSolarWinds.MSP.CacheServiceconfig. This can lead to code execution by changing the CacheService.xml SISServerURL parameter.

The default installation path of the TwinCAT XAR 3.1 software in all versions is underneath C:TwinCAT. If the directory does not exist it and further subdirectories are created with permissions which allow every local user to modify the content. The default installation registers TcSysUI.exe for automatic execution upon log in of a user. If a less privileged user has a local account he or she can replace TcSysUI.exe. It will be executed automatically by another user during login. This is also true for users with administrative access. Consequently, a less privileged user can trick a higher privileged user into executing code he or she modified this way. By default Beckhoff’s IPCs are shipped with TwinCAT software installed this way and with just a single local user configured. Thus the vulnerability exists if further less privileged users have been added.

When constructing a permission prompt for WebRTC, a URI was supplied from the content process. This URI was untrusted, and could have been the URI of an origin that was previously granted permission; bypassing the prompt. This vulnerability affects Firefox < 78.

When “%2F” was present in a manifest URL, Firefox’s AppCache behavior may have become confused and allowed a manifest to be served from a subdirectory. This could cause the appcache to be used to service requests for the top level directory. This vulnerability affects Firefox < 78.
