Title: Leon J Breedt Pam-PGSQL Remote SQL Query Manipulation Vulnerability
Severity: HIGH
Description:
Leon J Breedt's 'pam-pgsql' is a PAM authentication module to be used with PostgreSQL.
'pam-pgsql' is prone to a vulnerability which will allow SQL queries to be manipulated via any medium which requires a user to authenticate(HTTP, SSH, telnet, etc). Data that is included in SQL query strings is not adequately sanitized. It may be possible for users to modify the structure of SQL queries by carefully constructing variables containing metacharacters that will be included in the target query.
This issue allows the user to access resources that would normally be restricted, which may in turn provide an opportunity for the attacker to exploit other vulnerabilities that exist in the server. The attacker may be able to exploit this issue to gain unauthorized access to the host.
Affected Products:
- Leon J Breedt pam-pgsql 0.5.1
