Elevated Temp Directory Execution in 1E Client

In the affected version of the 1E Client, an ordinary user could subvert downloaded instruction resource files, e.g., to substitute a harmful script. by replacing a resource script file created by an instruction at run time with a malicious script. The 1E Client's temporary directory is now locked down in the released patch.

Resolution: This has been fixed in patch Q23094

This issue has also been fixed in the Mac Client in updated versions of Non-Windows release v8.1.2.62 - please re-download from the 1E Support site.

Customers with Mac Client versions higher than v8.1 will need to upgrade to v23.11 to remediate this vulnerability.
