CVE-2001-1241
Un-CGI 1.9 and earlier does not verify that a CGI script has the execution bits set before executing it, which allows remote attackers to execute arbitrary commands by directing Un-CGI to a document that begins with "#!" and the desired program name.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
