CVE-2002-0809: Mozilla Bugzilla

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

Bugzilla 2.14 before 2.14.2, and 2.16 before 2.16rc2, does not properly handle URL-encoded field names that are generated by some browsers, which could cause certain fields to appear to be unset, which has the effect of removing group permissions on bugs when buglist.cgi is provided with the encoded field names.

Affected products

• Mozilla Bugzilla: version 2.14 only; version 2.14.1 only; version 2.16 only
