CVE-2023-20250
Description
A vulnerability in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to improper validation of requests that are sent to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary code with root privileges on an affected device. To exploit this vulnerability, the attacker must have valid Administrator credentials on the affected device.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A stack overflow in the web-based management interface of Cisco Small Business RV series routers allows authenticated remote attackers to execute arbitrary code with root privileges.
Vulnerability
A stack overflow vulnerability exists in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers. The issue arises due to improper validation of requests sent to the interface. Affected firmware versions are those running on these devices at the time of disclosure (see advisory). [1]
Exploitation
An attacker must have valid Administrator credentials for the device. They can then send a crafted request to the web-based management interface over the LAN or WAN (if remote management is enabled). The crafted request triggers the stack overflow, leading to arbitrary code execution. [1]
Impact
Successful exploitation allows the attacker to execute arbitrary code with root privileges on the affected device. This grants full control over the router, potentially leading to data exfiltration, further network compromise, or denial of service. [1]
Mitigation
Cisco has not released firmware updates at the time of this advisory. No workarounds are available. Users should monitor the Cisco Security Advisory for updates and consider disabling remote management if not needed. [1]
