DSA-2091-1 squirrelmail -- No user-specific token implemented
- Date Reported:
- 12 Aug 2010
- Affected Packages:
- squirrelmail
- Vulnerable:
- Yes
- Security database references:
- In the Debian bugtracking system: Bug 543818.
In Mitre's CVE dictionary: CVE-2009-2964, CVE-2010-2813. - More information:
-
SquirrelMail, a webmail application, does not employ a user-specific token for webforms. This allows a remote attacker to perform a Cross Site Request Forgery (CSRF) attack. The attacker may hijack the authentication of unspecified victims and send messages or change user preferences among other actions, by tricking the victim into following a link controlled by the offender.
In addition, a denial-of-service was fixed, which could be triggered when a password containing 8-bit characters was used to log in (CVE-2010-2813).
For the stable distribution (lenny), these problems have been fixed in version 1.4.15-4+lenny3.1.
For the testing distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 1.4.21-1.
We recommend that you upgrade your squirrelmail packages.
- Fixed in:
-
Debian GNU/Linux 5.0 (lenny)
