CVE-2008-1320 in ASG-Sentry
Summary
by MITRE
Multiple buffer overflows in ASG-Sentry Network Manager 7.0.0 and earlier allow remote attackers to execute arbitrary code or cause a denial of service (crash) via (1) a long request to FxIAList on TCP port 6162, or (2) an SNMP request with a long community string to FxAgent on UDP port 6161.

The CVE-2008-1320 vulnerability affects ASG-Sentry Network Manager version 7.0.0 and earlier, presenting critical security risks through two distinct buffer overflow conditions that can be exploited remotely. This vulnerability resides in the network management software's handling of incoming network requests, specifically targeting two different service endpoints that operate on distinct network ports. The flaw demonstrates the classic pattern of insufficient input validation where the application fails to properly check the length of incoming data before processing it, leading to memory corruption that can be leveraged for malicious purposes.
The first vulnerability occurs when a malicious actor sends an excessively long request to the FxIAList service running on TCP port 6162. This buffer overflow condition arises from the application's inability to handle request data that exceeds predetermined buffer limits, causing memory corruption that can be exploited to execute arbitrary code on the affected system. The second vulnerability manifests through SNMP requests with overly long community strings sent to the FxAgent service on UDP port 6161, where similar buffer overflow conditions occur. Both attack vectors demonstrate the application's failure to implement proper bounds checking on user-supplied input data, creating opportunities for exploitation that align with CWE-121 buffer overflow conditions.
From an operational perspective, this vulnerability presents significant risks to network infrastructure security as it allows remote code execution without authentication requirements, enabling attackers to gain full control over the affected network management system. The impact extends beyond simple system compromise to include potential denial of service conditions that could disrupt network monitoring and management operations. Attackers can leverage these vulnerabilities to establish persistent access points within the network, potentially escalating privileges and moving laterally through the network infrastructure. The vulnerability's remote exploitability means that attackers do not need physical access to the system, making it particularly dangerous in enterprise environments where network management systems are often exposed to external networks.
The technical exploitation of these buffer overflows aligns with common attack patterns documented in the ATT&CK framework under the T1059 technique for command and script interpreter, as successful exploitation would enable adversaries to execute arbitrary commands on the compromised system. The vulnerability also relates to T1203 and T1499 techniques for legitimate credentials and network denial of service, as attackers could potentially use these vulnerabilities to gain unauthorized access or disrupt network operations. Organizations should consider implementing network segmentation and access controls to limit exposure of these services to untrusted networks, while also ensuring that network management systems are properly patched and updated to address these memory corruption vulnerabilities. The remediation approach should include immediate patching of the ASG-Sentry Network Manager software, implementation of network monitoring to detect suspicious traffic patterns, and configuration of proper input validation controls to prevent similar vulnerabilities from occurring in other network services.
The vulnerability demonstrates the critical importance of input validation in network security systems and highlights the potential consequences of inadequate bounds checking in network management applications. Organizations should conduct comprehensive vulnerability assessments of their network management infrastructure to identify similar buffer overflow conditions that may exist in other services or applications, as these types of memory corruption vulnerabilities remain prevalent in legacy network management systems. The security implications extend beyond immediate exploitation to include potential data exfiltration and system compromise that could affect the integrity of network monitoring data and overall network security posture.
