CVE-2006-0757 in HiveMail
Summary
by MITRE
Multiple eval injection vulnerabilities in HiveMail 1.3 and earlier allow remote attackers to execute arbitrary PHP code via (1) the contactgroupid parameter in addressbook.update.php, (2) the messageid parameter in addressbook.add.php, (3) the folderid parameter in folders.update.php, and possibly certain parameters in (4) calendar.event.php, (5) index.php, (6) pop.download.php, (7) read.bounce.php, (8) rules.block.php, (9) language.php, and (10) certain other scripts, as demonstrated by an addressbook.update.php request with a contactgroupid value of phpinfo() preceded by facilitators.

The vulnerability described in CVE-2006-0757 represents a critical server-side code injection flaw affecting HiveMail version 1.3 and earlier. This issue stems from improper input validation and sanitization mechanisms within the application's handling of user-supplied parameters. The vulnerability manifests as multiple eval injection points across various script files, allowing remote attackers to execute arbitrary PHP code on the affected server. The presence of eval injection vulnerabilities directly aligns with CWE-94, which defines the weakness of executing arbitrary code through insecure use of evaluation functions. These injection points exist in critical application components including address book management, folder operations, calendar event handling, and various other modules that process user input without proper sanitization.
The technical exploitation of this vulnerability occurs through the manipulation of specific HTTP parameters that are directly passed to eval() functions within the application's codebase. Attackers can craft malicious requests where parameters such as contactgroupid in addressbook.update.php, messageid in addressbook.add.php, and folderid in folders.update.php contain PHP code that gets executed server-side. The vulnerability demonstrates a classic lack of proper parameter validation and input sanitization, creating an environment where attacker-controlled data can be interpreted as executable code. The exploitation technique involves embedding PHP functions like phpinfo() within the parameter values, preceded by appropriate facilitators to ensure successful code execution. This approach leverages the fundamental security flaw of treating user input as executable code rather than as data, which represents a critical failure in application security design and data handling practices.
The operational impact of this vulnerability extends beyond simple code execution to encompass complete system compromise. Successful exploitation allows attackers to execute arbitrary commands on the web server, potentially leading to full system control, data exfiltration, and persistent backdoor installation. The vulnerability affects multiple application modules, increasing the attack surface and providing multiple potential entry points for malicious actors. The presence of injection points in calendar event handling, email processing scripts, and language configuration files means that attackers can compromise various aspects of the application's functionality. This vulnerability directly maps to ATT&CK technique T1059.007 for execution through PHP, and T1566 for initial access through web applications. Organizations running affected versions of HiveMail face significant risk of unauthorized access and potential data breaches, particularly in environments where the application processes sensitive user information or handles email communications.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary solution involves upgrading to a patched version of HiveMail that properly sanitizes all user input before processing. Additionally, implementing proper input validation and output encoding mechanisms throughout the application codebase is essential to prevent similar vulnerabilities from occurring. Security measures should include disabling or restricting the use of eval() functions in web applications, implementing proper parameter validation for all input fields, and employing secure coding practices that prevent user-supplied data from being interpreted as executable code. Organizations should also implement web application firewalls to detect and block suspicious parameter values, conduct regular security audits of application code, and establish proper input sanitization routines. The vulnerability underscores the importance of following secure coding guidelines and implementing defense-in-depth strategies to protect against injection attacks, particularly in applications that handle user input through web interfaces.
