CVE-2013-1899 — AI Deep Analysis Summary

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: A Parameter Injection flaw in PostgreSQL. 📉 **Consequences**: Remote attackers can cause Denial of Service (DoS) via file corruption.…

Q2Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: The vulnerability stems from how the system handles connection requests. Specifically, using a database name starting with a hyphen (**-**) triggers the injection.…

Q3Who is affected? (Versions/Components)

📦 **Affected Versions**: • PostgreSQL **9.2.x** (before 9.2.4) • PostgreSQL **9.1.x** (before 9.1.9) • PostgreSQL **9.0.x** (before 9.0.13) ⚠️ All earlier versions in these branches are at risk.

Q4What can hackers do? (Privileges/Data)

💀 **Attacker Capabilities**: • **Unauthenticated**: Can trigger DoS (file destruction). • **Authenticated**: Can **modify configuration settings** and **execute arbitrary code** on the server.…

Q5Is exploitation threshold high? (Auth/Config)

🔐 **Exploitation Threshold**: • **DoS**: Low (Remote). • **Code Execution**: Medium/High. Requires **remote authentication**. You must have valid database credentials to exploit the code execution aspect.

Q6Is there a public Exp? (PoC/Wild Exploitation)

🔍 **Public Exploit**: The provided data lists **no specific PoC or public exploit code** (pocs array is empty). However, vendor advisories (Debian, Ubuntu, SUSE) confirm the vulnerability exists and is actionable.

Q7How to self-check? (Features/Scanning)

🔎 **Self-Check**: 1. Check your PostgreSQL version against the affected list. 2. Monitor for unusual file corruption or DoS events. 3. Scan for connection attempts using database names starting with **-**.

Q8Is it fixed officially? (Patch/Mitigation)

✅ **Official Fix**: **Yes**. Patches are available. • Debian: DSA-2658 • Ubuntu: USN-1789-1 • SUSE: openSUSE-SU-2013:0627 & 0633 👉 **Action**: Update to the fixed versions immediately.

Q9What if no patch? (Workaround)

🛑 **No Patch Workaround**: • **Restrict Access**: Limit database connections to trusted IPs only. • **Input Sanitization**: Ensure application layer rejects database names starting with **-**. • **Least Privilege**: Ens…

Q10Is it urgent? (Priority Suggestion)

⚡ **Urgency**: **HIGH**. Although auth is required for code execution, the ability to modify configs and run arbitrary code is severe. The DoS risk is also significant. **Patch immediately** if running affected versions.
