## Technical details

The ConvExpr function in CGM CLININET unsafely evaluates Perl expressions when processing RTF document content (CWE-94: Code Injection). An authenticated, high-privileged attacker can craft malicious Perl expressions that are executed with root privileges, bypassing normal security controls. The vulnerability is confirmed in versions up to 2026.MS3, though later versions may also be affected; no patch is currently documented.
