Description
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.

Can you explain this vulnerability to me?

CVE-2026-5495 is a remote code execution vulnerability in Labcenter Electronics Proteus related to the parsing of PDSPRJ files.

The vulnerability occurs because the software does not properly validate user-supplied data, which leads to an out-of-bounds write past the end of an allocated buffer.

An attacker can exploit this flaw by tricking a user into visiting a malicious webpage or opening a malicious file, which then allows the attacker to execute arbitrary code with the privileges of the current process.


How can this vulnerability impact me? :

This vulnerability can have serious impacts because it allows remote attackers to execute arbitrary code on affected systems.

Successful exploitation could lead to full compromise of the affected application process, potentially allowing attackers to steal data, install malware, or disrupt system operations.

Since exploitation requires user interaction, the risk depends on users opening malicious files or visiting malicious websites.


What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, avoid opening PDSPRJ files from untrusted or unknown sources and do not visit suspicious or untrusted webpages that might deliver malicious PDSPRJ files.

Ensure that user interaction is minimized with potentially malicious content, as exploitation requires user action such as opening a malicious file or visiting a malicious page.

Apply any available patches or updates from Labcenter Electronics Proteus once they are released to fix this out-of-bounds write vulnerability.
