CVE-2005-4852: Ez Publish

Medium severity, CVSS 5.0. EPSS: 1.1% chance of exploitation in the next 30 days.

The siteaccess URIMatching implementation in eZ publish 3.5 through 3.8 before 20050812 converts all non-alphanumeric characters in a URI to '_' (underscore), which allows remote attackers to bypass access restrictions by inserting certain characters in a URI, as demonstrated by a request for /admin:de, which matches a rule allowing only /admin_de to access /admin.

Affected products

• Ez Ez Publish: from 3.5.0, before 3.5.8 (fixed in 3.5.8)
