Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Parameter Injection flaw in PostgreSQL. π **Consequences**: Remote attackers can cause Denial of Service (DoS) via file corruption.β¦
π‘οΈ **Root Cause**: The vulnerability stems from how the system handles connection requests. Specifically, using a database name starting with a hyphen (**-**) triggers the injection.β¦
π¦ **Affected Versions**: β’ PostgreSQL **9.2.x** (before 9.2.4) β’ PostgreSQL **9.1.x** (before 9.1.9) β’ PostgreSQL **9.0.x** (before 9.0.13) β οΈ All earlier versions in these branches are at risk.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: β’ **Unauthenticated**: Can trigger DoS (file destruction). β’ **Authenticated**: Can **modify configuration settings** and **execute arbitrary code** on the server.β¦
π **Exploitation Threshold**: β’ **DoS**: Low (Remote). β’ **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)
π **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)
π **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)
β **Official Fix**: **Yes**. Patches are available. β’ Debian: DSA-2658 β’ Ubuntu: USN-1789-1 β’ SUSE: openSUSE-SU-2013:0627 & 0633 π **Action**: Update to the fixed versions immediately.
β‘ **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.
