What is CVE-2023-25135?

An unauthenticated remote attacker can exploit a vulnerability in vBulletin versions prior to 5.6.9 PL1 by sending a specially crafted HTTP request. This vulnerability stems from improper handling of serialized data, enabling the attacker to potentially execute arbitrary code on the server. The affected versions include 5.6.7 PL1 and 5.6.8 PL1, which have been patched in subsequent releases. Users are advised to upgrade to secure their systems against potential exploitation.
