CVE-2025-13780 Scanner for pgAdmin 4
=====================================
This scanner checks if a pgAdmin 4 instance is vulnerable to the
regex bypass vulnerability that allows Remote Code Execution via
the restore functionality.
Vulnerability Details:
- The regex `(^|\n)[ \t]*\\` is used to detect psql meta-commands
- This regex can be bypassed using:
1. UTF-8 BOM prefix (\xef\xbb\xbf)
2. CRLF injection (\n\r)
- When bypassed, attackers can execute shell commands via \! meta-command
Usage:
python3 scanner.py <target_url>
python3 scanner.py -f targets.txt
python3 scanner.py <target_url> --email EMAIL --password PASSWORD
Examples:
python3 scanner.py http://localhost:5050
python3 scanner.py -f targets.txt -o results.json --json
python3 scanner.py http://target:5050 -e admin@cve2025-13780.com -p admin
