Vulnerability Details
The official description identifies this vulnerability as an out-of-bounds write that can occur due to improper handling of input sizes within the azerothcore azerothcore-wotlk's zlib modules. The issue is associated with program files inflate.C.
This vulnerability has a CVSS score of 10, indicating a critical severity level, which means that it poses a significant threat to confidentiality, integrity, and availability.
The affected product is azerothcore, with the vulnerability impacting all versions prior to the vendor patch, specifically up to v4.0.0. This vulnerability falls under the Common Weakness Enumeration (CWE) categories CWE-120 and CWE-787.
The publication date for this vulnerability was January 27, 2026, and it continues to be analyzed for further implications.
Technical Analysis
The root cause of CVE-2026-24793 lies in the buffer handling mechanisms within the affected software, specifically allowing writes beyond allocated memory boundaries. This can lead to memory corruption, crashes, or execution of arbitrary code.
The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely without requiring physical access to the vulnerable system. The attack complexity is assessed as low, and no user interaction is required to initiate an attack.
Given that no privileges are required to exploit this vulnerability, attackers can potentially leverage it to gain access to sensitive data or disrupt service availability.
The impacts on confidentiality, integrity, and availability are high, as exploiting this vulnerability could allow attackers to read, modify, or destroy data, leading to severe operational disruptions.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is significant. Organizations using azerothcore azerothcore-wotlk risk exposure to unauthorized access and data breaches if this vulnerability is not mitigated promptly.
The blast radius potential is high due to the widespread use of azerothcore in various environments, meaning that exploitation could lead to cascading failures across interconnected systems.
Given the CVSS score of 10 and the absence of known exploits, organizations must consider this vulnerability as an urgent priority. The urgency for remediation is critical to prevent potential exploitation.
