CVE-2005-1283 in Mail Server
Summary
by MITRE
Multiple directory traversal vulnerabilities in Argosoft Mail Server Pro 1.8.7.6 allow remote authenticated users to (1) read arbitrary files via the UIDL parameter to the msg script or (2) copy or move the user s .eml file to arbitrary locations via the delete script, a different vulnerability than CVE-2005-0367.

The CVE-2005-1283 vulnerability affects Argosoft Mail Server Pro version 1.8.7.6 and represents a critical directory traversal flaw that enables authenticated remote attackers to access sensitive system files and manipulate user data. This vulnerability manifests in two distinct attack vectors that exploit improper input validation within the mail server's message handling scripts. The first vulnerability occurs when processing the UIDL parameter in the msg script, while the second vulnerability involves the delete script which allows manipulation of user .eml files. Both issues stem from inadequate sanitization of user-supplied input parameters that are directly incorporated into file system operations without proper validation or escaping mechanisms.
The technical exploitation of these vulnerabilities relies on the server's failure to properly validate and sanitize input parameters before using them in file system operations. When an authenticated user sends a specially crafted request containing directory traversal sequences such as ../ or ..\, the mail server processes these sequences without proper sanitization, allowing attackers to navigate outside the intended directory boundaries. This creates a path traversal condition that enables access to arbitrary files on the server's file system. The vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. These attacks exploit the fundamental assumption that user input is trustworthy and can be directly used in file operations without proper validation.
The operational impact of CVE-2005-1283 extends beyond simple file access to include potential data exfiltration and system compromise. An attacker with valid credentials can use the first vulnerability to read system configuration files, password hashes, or other sensitive data stored on the server. The second vulnerability allows for more sophisticated attacks including the ability to move or copy user email files to arbitrary locations, potentially enabling attackers to overwrite critical system files or create backdoors. This could result in privilege escalation, persistent access, or complete system compromise. The vulnerability operates at the application layer and can be classified under ATT&CK technique T1059.007 for command and scripting interpreter, specifically web shell deployment, when combined with other attack vectors. The authenticated nature of the attack means that compromise can occur through legitimate user credentials, making detection more challenging.
Mitigation strategies for CVE-2005-1283 should focus on implementing proper input validation and sanitization across all user-supplied parameters that are used in file system operations. Organizations should ensure that all directory traversal sequences are properly filtered or escaped before being processed by the mail server. The most effective immediate fix involves patching the Argosoft Mail Server Pro to version 1.8.7.7 or later, which contains the necessary security fixes for these vulnerabilities. Additionally, implementing network segmentation and access controls can limit the impact of such vulnerabilities by restricting access to the mail server to only authorized users and systems. Regular security audits and input validation testing should be conducted to prevent similar vulnerabilities from being introduced in future applications. The vulnerability demonstrates the critical importance of validating all user inputs and implementing proper access controls, principles that align with security frameworks such as the OWASP Top Ten and NIST cybersecurity guidelines.
