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

The CVE-2024-49342 vulnerability affects IBM Informix Dynamic Server versions 12.10 and 14.10. The server uses inadequate account lockout settings, which could potentially allow remote attackers to brute force account credentials. This vulnerability is critical as it can lead to system compromise or data leakage if exploited.<\/p>\n

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

CVE ID: CVE-2024-49342
\nSeverity: High (7.5 CVSS)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

IBM Informix Dynamic Server | 12.10
\nIBM Informix Dynamic Server | 14.10<\/p>\n

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

The exploit takes advantage of the inadequate account lockout settings in IBM Informix Dynamic Server. Without appropriate lockout mechanisms, an attacker can engage in a brute force attack, systematically trying all possible combinations for account credentials until successful. This vulnerability can be exploited remotely, without any user interaction.<\/p>\n

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

Below is a conceptual example of how this vulnerability might be exploited.<\/p>\n

for password in `cat dictionary.txt`\ndo\necho Trying password: $password\ncurl --data \"username=admin&password=$password\" http:\/\/target.example.com\/login\nif [ \"$?\" -eq \"0\" ]; then\necho \"Found password: $password\"\nbreak\nfi\ndone<\/code><\/pre>\n
In this example, the attacker uses a script to go through a list of common passwords (`dictionary.txt`). The script sends HTTP POST requests with the username and password to the login endpoint of the target server. If the server responds with a success message, the script halts and the password is found.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation, configured to detect and block multiple failed login attempts within a certain period of time.<\/p>\n","protected":false},"excerpt":{"rendered":"
