GLSA-200406-09 : Horde-Chora: Remote code execution
High Nessus Plugin ID 14520
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200406-09 (Horde-Chora: Remote code execution)
A vulnerability in the diff viewer of Chora allows an attacker to inject shellcode. An attacker can exploit PHP's file upload functionality to upload a malicious binary to a vulnerable server, chmod it as executable, and run the file.
An attacker could remotely execute arbitrary binaries with the permissions of the PHP script, conceivably allowing further exploitation of local vulnerabilities and remote root access.
There is no known workaround at this time.
SolutionAll users are advised to upgrade to the latest version of Chora:
# emerge sync # emerge -pv '>=www-apps/horde-chora-1.2.2' # emerge '>=www-apps/horde-chora-1.2.2'
