CVE-2009-2367 in StorCenter Pro
Summary
by MITRE
cgi-bin/makecgi-pro in Iomega StorCenter Pro generates predictable session IDs, which allows remote attackers to hijack active sessions and gain privileges via brute force guessing attacks on the session_id parameter.

The vulnerability identified as CVE-2009-2367 affects the Iomega StorCenter Pro storage device, specifically within the cgi-bin/makecgi-pro component. This issue represents a significant security weakness in the device's session management mechanism that directly impacts the integrity and confidentiality of user sessions. The vulnerability stems from the predictable nature of session identifiers generated by the system, creating a pathway for malicious actors to exploit the authentication mechanism through systematic guessing attacks.
The technical flaw resides in the session ID generation algorithm used by the makecgi-pro script, which produces identifiers that follow predictable patterns rather than employing cryptographically secure random number generation. This weakness allows remote attackers to systematically guess valid session IDs through brute force techniques, effectively enabling session hijacking attacks. The predictable session IDs compromise the fundamental security principle of session isolation, permitting unauthorized users to impersonate legitimate session holders and gain elevated privileges within the system. This vulnerability directly maps to CWE-1037, which addresses weak session ID generation, and represents a classic example of insufficient randomness in security-critical functions.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with the ability to escalate privileges and potentially gain administrative control over the storage device. Once an attacker successfully hijacks an active session, they can perform operations such as modifying storage configurations, accessing sensitive data, changing user accounts, and potentially using the device as a pivot point for attacks on other systems within the network. The remote nature of this attack vector means that adversaries do not require physical access to the device or network proximity, making the vulnerability particularly dangerous in enterprise environments where such storage devices may be exposed to external networks.
Security professionals should implement immediate mitigations including strengthening session ID generation to utilize cryptographically secure random number generators, implementing proper session management protocols, and establishing session timeout mechanisms. Network segmentation and access controls should be enforced to limit exposure of the vulnerable device to untrusted networks. The ATT&CK framework categorizes this vulnerability under T1566 for credential access through brute force techniques, highlighting the need for robust authentication mechanisms and monitoring of suspicious session activity. Organizations should also consider implementing intrusion detection systems that can identify and alert on unusual session ID guessing patterns, as well as conducting regular security assessments to identify similar predictable pattern vulnerabilities in other components of their infrastructure.
