CVE-2006-3392: Usermin

Medium severity, CVSS 5.0. EPSS: 79.5% chance of exploitation in the next 30 days.

Webmin before 1.290 and Usermin before 1.220 calls the simplify_path function before decoding HTML, which allows remote attackers to read arbitrary files, as demonstrated using "..%01" sequences, which bypass the removal of "../" sequences before bytes such as "%01" are removed from the filename. NOTE: This is a different issue than CVE-2006-3274.

Affected products

• Usermin Usermin: up to and including 1.210
• Webmin Webmin: up to and including 1.2.80
