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.
Multiple buffer overflow vulnerabilities in Cisco Small Business RV series routers allow authenticated remote attackers to execute arbitrary code or cause DoS.
Vulnerability
Multiple buffer overflow vulnerabilities exist in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 routers [1]. These vulnerabilities are due to improper validation of user-supplied input. An authenticated attacker can trigger the overflow by sending crafted HTTP requests. All firmware versions prior to the fixed releases are affected.
Exploitation
To exploit these vulnerabilities, an attacker must have valid administrator credentials on the affected device [1]. The attacker sends specially crafted HTTP requests to the web-based management interface, triggering a buffer overflow.
Impact
Successful exploitation allows 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 [1].
Mitigation
Cisco has released free software updates to address these vulnerabilities [1]. Customers should upgrade to the latest firmware version for their device. No workarounds are available.
