GLSA-200411-33 : TWiki: Arbitrary command execution

Critical Nessus Plugin ID 15827


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200411-33 (TWiki: Arbitrary command execution)

The TWiki search function, which uses a shell command executed via the Perl backtick operator, does not properly escape shell metacharacters in the user-provided search string.
Impact :

An attacker can insert malicious commands into a search request, allowing the execution of arbitrary commands with the privileges of the user running TWiki (usually the Web server user).
Workaround :

There is no known workaround at this time.


All TWiki users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-apps/twiki-20040902'
