Cisco Small Business RV Series Routers Management Interface Remote Command Execution and Denial of Service Vulnerabilities
Description
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly. These vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on the affected device.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Cisco Small Business RV series routers have multiple vulnerabilities in the web-based management interface allowing authenticated remote attackers to execute arbitrary code or cause denial of service.
Vulnerability
The vulnerabilities reside in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 routers. They are due to improper validation of user-supplied input. An attacker must have valid administrator credentials to reach the vulnerable code path. [1]
Exploitation
An authenticated attacker with administrator privileges can exploit these vulnerabilities by sending crafted HTTP requests to the affected device. No additional user interaction is required. The attacker can trigger the improper input validation to execute arbitrary commands or cause a device reload. [1]
Impact
Successful exploitation allows the attacker to execute arbitrary code as the root user on the underlying operating system, leading to full compromise of the device. Alternatively, the attacker can cause the device to reload, resulting in a denial of service (DoS) condition. [1]
Mitigation
Cisco has released free software updates to address these vulnerabilities. Affected users should upgrade to the fixed firmware versions as specified in the Cisco Security Advisory [1]. No workarounds are available. The vulnerabilities are not listed in the Known Exploited Vulnerabilities (KEV) catalog as of the publication date. [1]
