CVE-2022-24861
📋 TL;DR
Databasir 1.01 has a remote code execution vulnerability where JDBC drivers uploaded by users are not validated before use. This allows any authenticated user to execute arbitrary code on the server. All users with access to the system are affected.
💻 Affected Systems
- Databasir
📦 What is this software?
Databasir by Databasir
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining root/administrator privileges, data exfiltration, and persistent backdoor installation.
Likely Case
Attacker executes arbitrary code with application service account privileges, potentially accessing database credentials and sensitive data.
If Mitigated
Limited impact with proper network segmentation and minimal privileges, but still significant due to code execution capability.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated.
