CVE-2025-1094 — AI Deep Analysis Summary

🚨 **Essence**: CVE-2025-1094 is a critical SQL Injection flaw in PostgreSQL's `libpq` client library. 📉 **Consequences**: Improper handling of quote syntax allows attackers to bypass input boundaries.…

🛡️ **Root Cause**: CWE-149 (Improper Neutralization of Input During Web Page Generation). The flaw lies in `libpq` escape functions (`PQescapeLiteral`, `PQescapeString`, etc.).…

👥 **Affected**: PostgreSQL systems using `libpq` client libraries. 📦 Specifically, applications that use the result of escape functions to construct input for `psql` (the interactive terminal).…

🕵️ **Attacker Capabilities**: Hackers can inject malicious SQL commands. 💻 They can read sensitive files (e.g., `/etc/passwd`). 🚀 Crucially, they can escalate to **Remote Code Execution (RCE)**.…

📊 **Exploitation Threshold**: CVSS Vector: `AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`. 🎯 **Auth**: No privileges required (PR:N). 🌍 **Network**: Remote (AV:N). 🧠 **Complexity**: High (AC:H).…

💣 **Public Exploits**: YES. Multiple PoCs are available on GitHub. 🔗 Examples: `soltanali0/CVE-2025-1094-Exploit` and `shacojx/CVE-2025-1094-Exploit`. 📜 These scripts demonstrate SQLi → WebSocket Hijacking → RCE.…

🔍 **Self-Check**: Scan for PostgreSQL instances using `libpq` with `BIG5` encoding settings. 🧪 Test if application input is passed directly to `psql` after escaping.…

🩹 **Official Fix**: Refer to the official PostgreSQL security page: `https://www.postgresql.org/support/security/CVE-2025-1094/`. 📅 Published: 2025-02-13.…

🚧 **No Patch Workaround**: Avoid using `psql` with dynamically constructed inputs from escaped strings. 🛑 Disable `BIG5` encoding if not strictly necessary.…

🔥 **Urgency**: CRITICAL. 🚨 CVSS Score indicates High Impact (Confidentiality, Integrity, Availability). 🏃‍♂️ Immediate action required. 🛡️ Patching is essential to prevent RCE.…
