CVE-2018-0342
Description
A vulnerability in the configuration and monitoring service of the Cisco SD-WAN Solution could allow an authenticated, local attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete bounds checks for data that is provided by the configuration and monitoring service of the affected solution. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, which could allow the attacker to execute arbitrary code with root privileges on the device or cause the vDaemon listening service to reload and result in a DoS condition on the device. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers, vEdge Cloud Router Platform, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi70003.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Buffer overflow in Cisco SD-WAN vDaemon allows authenticated local attacker to execute arbitrary code with root privileges or cause DoS.
Vulnerability
A buffer overflow vulnerability exists in the configuration and monitoring service (vDaemon) of the Cisco SD-WAN Solution [1]. The issue stems from incomplete bounds checks when processing data from authenticated local users. Affected products include vBond Orchestrator, vEdge routers (100, 1000, 2000, 5000 series), vEdge Cloud Router, vManage, and vSmart Controller Software, all running software prior to Release 18.3.0 [1].
Exploitation
An authenticated local attacker can exploit this vulnerability by sending specially crafted data to the vDaemon listening service on the affected device. No additional user interaction is required beyond authentication. The malicious data triggers a buffer overflow condition in the vDaemon process [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code with root privileges, gaining full control of the device. Alternatively, the attacker can cause the vDaemon service to reload, resulting in a denial of service (DoS) condition [1].
Mitigation
Cisco has addressed this vulnerability in Release 18.3.0 of the Cisco SD-WAN Solution [1]. Users should upgrade to this release or later. No workarounds are available [1]. The Cisco bug ID is CSCvi70003.
