CVE-2000-1058 in Openview Network Node Manager
Summary
by MITRE
Buffer overflow in OverView5 CGI program in HP OpenView Network Node Manager (NNM) 6.1 and earlier allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, in the SNMP service (snmp.exe), aka the "Java SNMP MIB Browser Object ID parsing problem."

The vulnerability identified as CVE-2000-1058 represents a critical buffer overflow flaw within the OverView5 CGI program component of HP OpenView Network Node Manager version 6.1 and earlier. This security weakness specifically targets the SNMP service (snmp.exe) and manifests through the Java SNMP MIB Browser Object ID parsing functionality. The flaw exists in the handling of malformed Object Identifier (OID) values during SNMP MIB browsing operations, creating an exploitable condition that can be leveraged by remote attackers to compromise system integrity.
This buffer overflow vulnerability operates through the manipulation of input parameters within the SNMP service's MIB browser component. When the OverView5 CGI program processes malformed OID values, it fails to properly validate input length and structure, leading to memory corruption that can result in program termination or arbitrary code execution. The vulnerability is classified as a classic stack-based buffer overflow with CWE-121, where insufficient bounds checking allows attackers to overwrite adjacent memory locations. The attack vector is remote and requires no authentication, making it particularly dangerous in networked environments where SNMP services are exposed to external networks.
The operational impact of this vulnerability extends beyond simple denial of service to potentially enable complete system compromise. An attacker exploiting this flaw could cause the SNMP service to crash, resulting in service disruption, or more critically, execute arbitrary code with the privileges of the snmp.exe process. This could lead to unauthorized access to network management functions, data exfiltration, or further escalation within the network infrastructure. The vulnerability affects the core network management capabilities of HP OpenView NNM, potentially compromising network visibility and control mechanisms that organizations rely upon for system monitoring and management.
Mitigation strategies for CVE-2000-1058 should focus on immediate patching of affected HP OpenView Network Node Manager installations to version 6.2 or later, which contains the necessary security fixes. Organizations should also implement network segmentation to limit access to SNMP services, disable unnecessary SNMP functionality, and monitor for anomalous OID parsing attempts. Network administrators should consider implementing intrusion detection systems capable of identifying suspicious SNMP traffic patterns and establishing strict access controls for SNMP service endpoints. The vulnerability demonstrates the importance of input validation in network management applications and aligns with ATT&CK technique T1059.007 for command and scripting interpreter execution, as successful exploitation could enable attackers to execute arbitrary commands on affected systems. Additionally, this vulnerability highlights the need for regular security assessments of network management infrastructure, as the flaw exists within the SNMP service that is fundamental to network monitoring operations and represents a critical attack surface for adversaries seeking persistent access to enterprise networks.
