Sarg is vulnerable to the execution of arbitrary code when processed with untrusted input files.
| Package | net-analyzer/sarg on all architectures |
|---|---|
| Affected versions | < 2.2.5 |
| Unaffected versions | >= 2.2.5 |
Sarg (Squid Analysis Report Generator) is a tool that provides many informations about the Squid web proxy server users activities: time, sites, traffic, etc.
Sarg doesn't properly check its input for abnormal content when processing Squid log files.
A remote attacker using a vulnerable Squid as a proxy server or a reverse-proxy server can inject arbitrary content into the "User-Agent" HTTP client header, that will be processed by sarg, which will lead to the execution of arbitrary code, or JavaScript injection, allowing Cross-Site Scripting attacks and the theft of credentials.
There is no known workaround at this time.
All sarg users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/sarg-2.2.5"
