CVE-2009-1151 is a critical vulnerability affecting phpMyAdmin versions 2.11.x before 2.11.9.5 and 3.x before 3.1.3.1. This vulnerability allows remote attackers to inject arbitrary PHP code into a configuration file via a crafted POST request to the setup script, setup.php. The potential impact of this vulnerability is severe, as it enables attackers to execute arbitrary code on the server hosting phpMyAdmin.
The CVSS score for this vulnerability is 9.8, indicating its critical severity. Organizations utilizing affected versions of phpMyAdmin must recognize the immediate risk posed by this vulnerability and take appropriate action to remediate it. Given its high profile, this vulnerability may attract attention from malicious actors seeking to exploit unpatched systems.
Risk to organizations includes unauthorized access to sensitive data and potential complete server compromise. Therefore, organizations should prioritize patching immediately.
As of now, there is confirmed exploit availability, with multiple proof-of-concept (PoC) exploits found in the wild, indicating that attackers are actively looking to leverage this vulnerability. Organizations should act swiftly to mitigate this risk.
Vulnerability Details
The vulnerability arises from static code injection in setup.php of phpMyAdmin, allowing attackers to manipulate configuration files. The official CVE description highlights that this vulnerability specifically affects versions of phpMyAdmin that are prior to 2.11.9.5 and 3.1.3.1. The severity of this vulnerability, classified as critical, is underscored by its CVSS score of 9.8.
The vulnerability type is categorized under CWE-94: Improper Control of Generation of Code ('Code Injection'). The potential impacts on confidentiality, integrity, and availability are all classified as high, indicating a serious threat to systems running affected versions.
The vulnerability was published on March 26, 2009, and is part of the analyzed vulnerabilities concerning phpMyAdmin and Debian Linux.
Technical Analysis
The root cause of CVE-2009-1151 lies in the failure of phpMyAdmin's setup script to properly validate input. This flaw allows attackers to exploit the script by sending specially crafted POST requests, thereby injecting arbitrary PHP code into the configuration file. The attack vector is over the network, and the complexity of the attack is low, requiring no privileges or user interaction.
To exploit this vulnerability, attackers need only send a crafted request, which means that a wide range of users may be affected. The potential for elevated privileges and unauthorized access to sensitive information makes this vulnerability a significant concern.
The confidentiality impact is high, as attackers could potentially access sensitive data. Similarly, the integrity impact is high, allowing for unauthorized modifications to configurations and other critical files. The availability impact is also high, as attackers could disrupt services by manipulating critical components.
Risk & Impact Analysis
Organizations using the affected versions of phpMyAdmin are at substantial risk. The ability for remote attackers to inject arbitrary code means that the exposure can lead to severe consequences, including data breaches, service disruptions, and unauthorized access to sensitive information.
The blast radius is significant, as many installations of phpMyAdmin are often used in conjunction with other systems that may have access to sensitive data. Therefore, the urgency assessment based on the critical CVSS score, combined with known exploitation data, suggests immediate action is essential.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The affected versions of phpMyAdmin include versions 2.11.x before 2.11.9.5 and 3.x before 3.1.3.1. Additionally, Debian Linux versions 4.0 and 5.0 are also vulnerable due to their inclusion of affected phpMyAdmin versions.
Mitigation & Remediation
Organizations are urged to apply updates per vendor instructions immediately. The latest secure versions of phpMyAdmin should be installed to mitigate this vulnerability. If immediate patching is not feasible, consider implementing application firewall rules to block malicious requests targeting the setup script.
Additionally, organizations should consider performing a thorough security assessment of their phpMyAdmin installations, including configuration hardening and regular security audits.
Application security assessment services can help identify and remediate vulnerabilities effectively.
Detection Guidance
Organizations should monitor logs for any unusual activity related to phpMyAdmin, particularly any unauthorized access attempts or changes to configuration files. Behavioral anomalies such as unexpected script executions may also indicate exploitation attempts.
