Technical Analysis
CVE-2026-113404 describes an insecure deserialization vulnerability in Uniong WebITR, affecting versions from 0 through 2_1_0_34. Authenticated remote attackers can leverage a hard-coded cryptographic key to craft malicious serialized data, which when submitted to the server, leads to arbitrary code execution. This vulnerability is classified under CWE-502 (Insecure Deserialization) and CWE-321 (Use of Hard-coded Cryptographic Key). The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required beyond authentication, no user interaction, and high impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows authenticated remote attackers to execute arbitrary code on the server, potentially compromising confidentiality, integrity, and availability of the affected system. This could lead to full system compromise depending on the privileges of the WebITR service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to authenticated users and monitor for suspicious activity related to serialized data submission. Avoid using hard-coded cryptographic keys and consider implementing additional input validation or deserialization protections.
