CVE-2026-5494: CWE-787: Out-of-bounds Write in Labcenter Electronics Proteus
Labcenter Electronics Proteus PDSPRJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Labcenter Electronics Proteus. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of PDSPRJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25719.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-5494) affects Labcenter Electronics Proteus 8.17 SP5 and is caused by improper validation of user-supplied data in PDSPRJ file processing. Specifically, it results in an out-of-bounds write (CWE-787) that can be exploited remotely to execute arbitrary code. The attack vector requires user interaction, such as opening a crafted file or visiting a malicious page. The CVSS v3.0 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. The vulnerability was reported by ZDI as ZDI-CAN-25719. No patch or official remediation has been published yet.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code within the context of the current user process, potentially leading to full compromise of the affected system. The vulnerability impacts confidentiality, integrity, and availability of the system. Exploitation requires user interaction, limiting the attack vector to scenarios where a user opens a malicious file or visits a malicious webpage.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid opening PDSPRJ files from untrusted sources and be cautious about visiting untrusted websites. Monitor vendor communications for updates on patches or mitigations.
