CVE-2015-1187 is a critical vulnerability affecting multiple D-Link and TRENDnet devices. This vulnerability allows remote attackers to execute arbitrary code via the ping_addr parameter to ping.ccp. The severity of this vulnerability is underscored by its CVSS score of 9.8, indicating a critical risk level.
With the potential for full system compromise, the urgency for organizations to address this vulnerability is high. Exploitation is possible over the network with no user interaction required, making this a significant threat to any organization using the affected devices.
Currently, the vulnerability is listed in the Known Exploited Vulnerabilities (KEV) catalog, further emphasizing the need for immediate action. Organizations are advised to disconnect affected products, as many are now end-of-life and no longer supported by the vendors.
The risk to organizations includes potential unauthorized access and control over their devices, which could lead to further network exploitation. Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability is classified under CWE-287 (Improper Authentication). The CVSS score of 9.8 indicates the severity level is critical. The affected products include a range of D-Link and TRENDnet firmware versions, highlighting the need for comprehensive vulnerability management in environments using these devices.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input in the ping tool, allowing attackers to inject malicious code. The attack vector is network-based, requiring low complexity and no privileges or user interaction. If exploited, confidentiality, integrity, and availability impacts are all rated as high, indicating severe consequences for affected systems.
Risk & Impact Analysis
The risk to organizations includes the potential for full system compromise, unauthorized access, and control over network resources. With a high likelihood of exploitation, organizations must assess their exposure to this vulnerability. Given its inclusion in the KEV catalog, organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
