CVE-2007-1062 in Unified Ip Conference Station 7936
Summary
by MITRE
The Cisco Unified IP Conference Station 7935 3.2(15) and earlier, and Station 7936 3.3(12) and earlier does not properly handle administrator HTTP sessions, which allows remote attackers to bypass authentication controls via a direct URL request to the administrative HTTP interface for a limited time

The vulnerability identified as CVE-2007-1062 affects Cisco Unified IP Conference Station models 7935 and 7936, specifically versions 3.2(15) and earlier for the 7935 model, and 3.3(12) and earlier for the 7936 model. This issue represents a critical authentication bypass flaw that stems from improper handling of administrative HTTP sessions within the web-based management interface of these telephony devices. The vulnerability resides in the session management mechanism that fails to adequately validate or track administrative access requests, creating a window of opportunity for unauthorized actors to exploit the system.
The technical flaw manifests when remote attackers can construct direct URL requests to the administrative HTTP interface without proper authentication credentials. This weakness allows unauthorized access to administrative functions that should normally require valid login credentials and session management. The vulnerability operates on a time-based window where the administrative interface remains accessible without proper authentication for a limited period after initial access attempts. This behavior aligns with CWE-287, which addresses improper authentication issues in software systems, specifically focusing on the inadequate handling of authentication sessions that can lead to privilege escalation and unauthorized system access.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass potential complete system compromise. Attackers who successfully exploit this vulnerability can gain administrative control over the conference station devices, enabling them to modify system configurations, access sensitive communications data, and potentially use the compromised devices as entry points for broader network attacks. This vulnerability particularly affects organizations that rely on these devices for secure voice communications and collaborative environments, as it undermines the fundamental security assumptions of the device's management interface. The time-based nature of the vulnerability means that even brief periods of unauthorized access can provide attackers with sufficient opportunity to execute malicious actions.
Organizations should implement immediate mitigations including applying the latest firmware updates from Cisco that address the session management flaw in the affected devices. Network segmentation strategies should be employed to isolate these devices from critical network segments, and access controls should be strengthened through proper network access control measures. The vulnerability demonstrates the importance of proper session management and authentication mechanisms in networked devices, aligning with ATT&CK technique T1078 for valid accounts and T1566 for credential harvesting. Administrators should also consider implementing network monitoring solutions to detect unauthorized access attempts and unusual traffic patterns that may indicate exploitation attempts against the administrative interfaces of these devices.
