Overview<\/strong><\/p>\n

The CVE-2025-33109 is a critical vulnerability that affects IBM i versions 7.2 through 7.6. This vulnerability could allow a bad actor to escalate privileges and execute a database procedure or function without required permissions. Moreover, this vulnerability could also lead to a denial of service for some database actions. This is a significant issue that requires immediate attention due to the potential for system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-33109
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Privilege escalation and potential denial of service<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

IBM i | 7.2, 7.3, 7.4, 7.5, and 7.6<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by taking advantage of an invalid database authority check in IBM i. A bad actor could execute a database procedure or function without having all required permissions, essentially bypassing the security measures in place. This could lead to a privilege escalation, granting the attacker access to sensitive data and system capabilities. Additionally, this exploit could also cause a denial of service for some database actions.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

This is a conceptual example of how the vulnerability might be exploited. This is not actual exploit code but an illustration of the potential attack mechanism.<\/p>\n

EXECUTE AS USER = 'low_privilege_user'\nGO\n-- This is a function\/procedure that should require higher privileges\nEXECUTE dbo.vulnerable_procedure\nGO<\/code><\/pre>\n
In this example, a low-privileged user is executing a database procedure that normally requires higher privileges. The invalid authority check in IBM i versions 7.2 through 7.6 allows this to happen without raising any security flags.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The best way to mitigate this vulnerability is by applying the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may provide temporary mitigation. However, this should not be considered a long-term solution, as it does not address the root cause of the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
