CVE-2005-0408 is a critical-severity flaw (CVSS 9.8) affecting citrusdb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
CitrusDB 0.3.6 and earlier generates easily predictable MD5 hashes of the user name for the id_hash cookie, which allows remote attackers to bypass authentication and gain privileges by calculating the MD5 checksum of the user name combined with the "boogaadeeboo" string, which is hard-coded in the $hidden_hash variable.
Why this priority
- Critical severity
- EPSS top 8%: very likely to be exploited
- Public exploit reference
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
