CVE-2007-1070 in ServerProtect
Summary
by MITRE
Multiple stack-based buffer overflows in Trend Micro ServerProtect for Windows and EMC 5.58, and for Network Appliance Filer 5.61 and 5.62, allow remote attackers to execute arbitrary code via crafted RPC requests to TmRpcSrv.dll that trigger overflows when calling the (1) CMON_NetTestConnection, (2) CMON_ActiveUpdate, and (3) CMON_ActiveRollback functions in (a) StCommon.dll, and (4) ENG_SetRealTimeScanConfigInfo and (5) ENG_SendEMail functions in (b) eng50.dll.

The vulnerability identified as CVE-2007-1070 represents a critical stack-based buffer overflow issue affecting multiple enterprise security products from Trend Micro and EMC. This flaw exists within the remote procedure call (RPC) processing functionality of ServerProtect for Windows and Network Appliance Filer systems, creating a significant attack surface that adversaries can exploit to gain unauthorized code execution privileges. The vulnerability stems from inadequate input validation within the TmRpcSrv.dll component, which processes RPC requests from remote clients without sufficient bounds checking mechanisms.
The technical implementation of this vulnerability involves specific function calls within two core libraries that handle different aspects of system management and security operations. The CMON_NetTestConnection, CMON_ActiveUpdate, and CMON_ActiveRollback functions in StCommon.dll represent the primary attack vectors, while the ENG_SetRealTimeScanConfigInfo and ENG_SendEMail functions in eng50.dll provide additional pathways for exploitation. These functions are designed to process network-based administrative commands but fail to properly validate the length and content of incoming data, allowing attackers to overflow the allocated stack buffers and overwrite critical program execution elements including return addresses and function pointers.
The operational impact of this vulnerability extends beyond simple remote code execution, as it enables attackers to compromise entire network infrastructure through carefully crafted RPC requests. The attack requires no authentication and can be executed from any remote location, making it particularly dangerous for enterprise environments where these security products are deployed. Successful exploitation allows threat actors to execute arbitrary code with the privileges of the affected service, potentially leading to complete system compromise, data exfiltration, and lateral movement within the network. This vulnerability directly maps to CWE-121 Stack-based Buffer Overflow, which is classified as a high-severity weakness in the Common Weakness Enumeration catalog, and aligns with attack patterns documented in the MITRE ATT&CK framework under the T1059.007 technique for execution through remote services.
Mitigation strategies for this vulnerability should focus on immediate patching of affected systems, as Trend Micro and EMC released security updates specifically addressing these buffer overflow conditions. Network segmentation and firewall rules should be implemented to restrict RPC traffic to only trusted administrative hosts, while monitoring systems should be configured to detect unusual RPC request patterns that might indicate exploitation attempts. Additionally, implementing application whitelisting policies and disabling unnecessary RPC services can reduce the attack surface. Organizations should also consider deploying intrusion detection systems that can identify malformed RPC requests targeting the vulnerable functions, and regular security assessments should validate that all affected components have been properly updated to prevent exploitation of this persistent vulnerability that could remain undetected for extended periods.
