CVE-2026-5495: 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-25720.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-5495) affects Labcenter Electronics Proteus 8.17 SP5 and is caused by an out-of-bounds write in the processing of PDSPRJ files due to insufficient validation of user input. An attacker can exploit this flaw by convincing a user to open a crafted PDSPRJ file or visit a malicious page, resulting in arbitrary code execution with the privileges of the current user. The CVSS 3.0 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. The vulnerability was reported by ZDI (ZDI-CAN-25720). No patch or official remediation has been disclosed as of the publication date.
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. Confidentiality, integrity, and availability of the system are all rated high impact. Exploitation requires user interaction, such as opening a malicious file or visiting 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 exercise caution when opening PDSPRJ files from untrusted sources and avoid visiting untrusted websites that could deliver malicious files. No official workaround or temporary fix has been published.
