Synopsis
Sarg is vulnerable to the execution of arbitrary code when processed with untrusted input files.Background
Sarg (Squid Analysis Report Generator) is a tool that provides many informations about the Squid web proxy server users activities: time, sites, traffic, etc.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
net-analyzer/sarg | < 2.2.5 | >= 2.2.5 | All supported architectures |
Description
Sarg doesn't properly check its input for abnormal content when processing Squid log files.
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All sarg users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/sarg-2.2.5"
