SQL Injection in Ghidra PostgreSQL Password Change Handler

Ghidra 11.0 before 12.1 contains a SQL injection vulnerability in the changePassword() method of PostgresFunctionDatabase that fails to escape double quotes in usernames interpolated into ALTER ROLE statements. Authenticated attackers can inject SQL commands via crafted username parameters in PasswordChange network messages to escalate to PostgreSQL superuser privileges and gain full database control.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

Ghidra 11.0 through 12.0 contains a critical SQL injection vulnerability in the changePassword() method of PostgresFunctionDatabase, where unescaped double quotes in usernames allow authenticated attackers to inject arbitrary SQL commands. By crafting malicious username parameters in PasswordChange network messages, attackers can manipulate ALTER ROLE statements to escalate privileges to PostgreSQL superuser, achieving complete database compromise. This vulnerability affects organizations using vulnerable Ghidra versions with PostgreSQL backends for collaborative reverse engineering and program analysis, where authenticated users—whether legitimate employees or compromised accounts—can pivot from standard access to full database control.

Casky.ai's 301 mapped skills detect this attack pattern by analyzing SQL injection indicators (CWE-89) combined with privilege escalation behaviors mapped to MITRE ATT&CK's TA0001 (Initial Access) and TA0043 (Resource Development). Practitioners using Casky would observe findings flagging: (1) unsanitized user input flowing into SQL query construction, (2) quote-based SQL escape bypass attempts in authentication contexts, (3) ALTER ROLE statement manipulation, and (4) privilege level transitions from authenticated user to superuser roles within PostgreSQL logs. Claude's extended reasoning correlates these signals to identify the complete attack chain—authentication → malicious payload injection → privilege escalation—enabling teams to prioritize patching and audit compromised database accounts before attackers establish persistence.
