CVE-1999-1053 EXPLOIT
7.5
HIGH · CVSS 2.0 · EPSS 85.2% (pctl 100)
Patch early
A public exploit exists.
Description
guestbook.pl cleanses user-inserted SSI commands by removing text between "<!--" and "-->" separators, which allows remote attackers to execute arbitrary commands when guestbook.pl is run on Apache 1.3.9 and possibly other versions, since Apache allows other closing sequences besides "-->".
