Description (CNA)
A flaw was found in mod_qos. An off-by-one pointer calculation error occurs when merging request body parameters with an existing URL query, which truncates the query string during security evaluation while leaving the actual request unchanged. An unauthenticated remote attacker could exploit this vulnerability by submitting a crafted request that conceals prohibited values from inspection, resulting in a bypass of configured security rules.
