CVE-2024-54176
📋 TL;DR
This vulnerability in IBM DevOps Deploy and UrbanCode Deploy allows authenticated users to access sensitive information about other users due to missing authorization checks. It affects multiple versions of both products. The risk is limited to authenticated users but could lead to information disclosure.
💻 Affected Systems
- IBM DevOps Deploy
- IBM UrbanCode Deploy
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could enumerate all user accounts, potentially obtaining usernames, roles, permissions, or other sensitive metadata that could facilitate further attacks.
Likely Case
An authenticated user with legitimate access could accidentally or intentionally view information about other users they shouldn't have access to, violating privacy and potentially revealing organizational structure.
If Mitigated
With proper access controls and monitoring, the impact is limited to information disclosure that doesn't include passwords or highly sensitive data.
🎯 Exploit Status
Exploitation requires authenticated access to the vulnerable systems. The vulnerability is in authorization logic, not authentication.
