CVE-2026-5495: CWE-787: Out-of-bounds Write in Labcenter Electronics Proteus
CVE-2026-5495 is a high-severity vulnerability in Labcenter Electronics Proteus version 8.17 SP5. It involves an out-of-bounds write during the parsing of PDSPRJ files, which can lead to remote code execution if a user opens a malicious file or visits a malicious page. Exploitation requires user interaction. The vulnerability arises from improper validation of user-supplied data, allowing an attacker to write beyond allocated memory and execute arbitrary code in the context of the current process. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-5495) affects Labcenter Electronics Proteus 8.17 SP5 and is caused by a lack of proper validation in the processing of PDSPRJ files. Specifically, it allows an out-of-bounds write (CWE-787) that can be exploited by remote attackers to execute arbitrary code with the privileges of the user running the application. Exploitation requires user interaction, such as opening a crafted file or visiting a malicious webpage. The CVSS v3.0 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, but user interaction needed, and impacts confidentiality, integrity, and availability.
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's confidentiality, integrity, and availability. Since user interaction is required, the risk is somewhat mitigated but remains significant due to the high impact of code execution.
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability. Users should exercise caution when opening PDSPRJ files from untrusted sources and avoid visiting untrusted web pages that might deliver malicious files. Monitor vendor advisories for updates regarding patches or official mitigations. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
