Overview
CVE-2025-1883 is a serious security vulnerability discovered in SOLIDWORKS eDrawings, affecting the Desktop 2025 release. This vulnerability resides in the OBJ file reading procedure and could lead to potentially catastrophic consequences if exploited. It is a type of Out-Of-Bounds Write vulnerability, a common but dangerous class of vulnerabilities that can lead to arbitrary code execution.
This vulnerability matters because SOLIDWORKS is a widely-used 3D CAD (computer-aided design) program, and eDrawings is a popular viewer and editor for SOLIDWORKS and other CAD files. An attacker exploiting this vulnerability could potentially compromise a system or leak sensitive data, impacting businesses and individuals alike.

How the Exploit Works
The exploit involves the manipulation of OBJ files, a standard 3D object format often used in 3D graphics and CAD. In the Desktop 2025 release of SOLIDWORKS eDrawings, the code handling the reading of OBJ files contains an out-of-bounds write vulnerability.
An attacker can craft a malicious OBJ file that, when opened in eDrawings, overflows the buffer allocated for the file’s data. This overflow can overwrite memory locations outside the intended bounds, potentially allowing the attacker to execute arbitrary code.
Conceptual Example Code
An example of a malicious OBJ file might look something like this:
v 1.000000 1.000000 1.000000
v 1.000000 1.000000 -1.000000
... (millions of lines) ...
v -1.000000 -1.000000 -1.000000This is a vastly simplified representation, but the basic idea is that the file contains far more vertex data (`v`) than the program expects, leading to a buffer overflow.
Users and system administrators are advised to apply the vendor’s patch to mitigate this vulnerability. In the absence of a patch, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation, although this is less ideal.
