Summary

CVE-2025-55194 is a medium-severity Uncaught Exception (CWE-248) vulnerability in Part-Db Project Part-Db. Its CVSS base score is 5.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 27th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-11 (Error Handling) — see the control section below for these in your framework.

Vulnerability Data

Part-DB is an open source inventory management system for electronic components. Prior to version 1.17.3, any authenticated user can upload a profile picture with a misleading file extension (e.g., .jpg.txt), resulting in a persistent 500 Internal Server Error when attempting…

to view or edit that user’s profile. This makes the profile permanently inaccessible via the UI for both users and administrators, constituting a Denial of Service (DoS) within the user management interface. This issue has been patched in version 1.17.3.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Authenticated users can exploit the avatar upload feature with misleading file extensions (e.g., .jpg.txt) to trigger uncaught exceptions, causing persistent 500 errors and denying access to user profiles via the UI, even for admins. This facilitates application-level denial of service via exploitation.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Enforces validation of file uploads (name, extension, content) to reject malformed inputs such as .jpg.txt before they reach the profile-handling code.

prevent

Requires graceful error handling so that an uncaught exception (CWE-248) from a bad profile picture does not produce a persistent 500 error and DoS the user-management UI.

prevent

Ensures the application fails in a known safe state rather than leaving the profile permanently inaccessible after an unexpected file-processing failure.

Secure SDLC practices explicitly require structured exception handling to prevent uncaught exceptions from reaching production.

detects

Security testing can detect uncaught exceptions before production deployment.

prevents

Secure development lifecycle includes exception-handling standards that reduce uncaught exceptions.

prevents

Application security requirements typically mandate robust error and exception handling.

prevents

Secure architecture principles call for centralized, comprehensive exception management.

prevents

Secure coding standards directly require catching and handling exceptions to prevent crashes or leaks.
