CVE-2006-0479: Pmwiki

Medium severity, CVSS 4.3. EPSS: 3.1% chance of exploitation in the next 30 days.

pmwiki.php in PmWiki 2.1 beta 20, with register_globals enabled, allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GPC variable and a GLOBALS[] variable with the same name, which causes PmWiki to unset the GLOBALS[] variable but not the GPC variable, which creates resultant vulnerabilities such as remote file inclusion and cross-site scripting (XSS).

Affected products

• Pmwiki Pmwiki: version 2.1_beta_20 only
