CVE-2022-20825 is a critical vulnerability affecting the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. This vulnerability allows an unauthenticated, remote attacker to execute arbitrary code or trigger unexpected device restarts, leading to a denial of service (DoS) condition. The root cause of this issue is insufficient user input validation of incoming HTTP packets.
With a CVSS score of 9.8, this vulnerability is classified as critical. It indicates a significant risk to organizations, especially since Cisco has not released any software updates to address this issue. Attackers may leverage this vulnerability to execute commands with root-level privileges, which poses a severe threat to the confidentiality, integrity, and availability of affected devices.
Organizations should prioritize patching immediately to mitigate potential risks associated with this vulnerability. The lack of an available patch increases the urgency for defenders to implement alternative security measures to protect their networks.
As of now, there are no confirmed public exploits or known active exploitation for this vulnerability, but the critical nature of the issue warrants immediate attention from security teams.
Organizations using affected Cisco routers must assess their exposure and take necessary actions to safeguard their systems against potential exploitation.
Vulnerability Details
The vulnerability in question stems from insufficient validation of user inputs in the web-based management interface of Cisco Small Business RV series routers. It has been reported that an attacker could exploit this vulnerability by sending a specially crafted HTTP request to the management interface. If successful, this could lead to arbitrary command execution on the device.
The CVSS score is 9.8, indicating a critical severity, with a high impact on confidentiality, integrity, and availability. The affected products include RV110W, RV130, RV130W, and RV215W routers. This vulnerability has been classified under CWE-121 and CWE-787, highlighting the underlying weaknesses related to improper validation and buffer errors.
Technical Analysis
The root cause of CVE-2022-20825 is traced back to inadequate user input validation in the web management interface. The attack vector is network-based, and the complexity is classified as low, which means it can be exploited without any significant prerequisites. Importantly, no user interaction is required to exploit this vulnerability.
Since the attacker does not need special privileges to execute this exploit, the risk escalates significantly. The confidentiality, integrity, and availability impacts are rated high, meaning that successful exploitation could lead to complete control over the affected devices.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is substantial. Given the critical nature of the vulnerability and the lack of available patches, organizations using Cisco RV series routers should take immediate action. Attackers may leverage this vulnerability to gain unauthorized access, leading to potential data breaches or service disruptions.
The blast radius potential is extensive, as this vulnerability affects multiple router models. Organizations must assess their network architecture and consider immediate remediation strategies to reduce exposure. The urgency assessment is critical, and organizations must prioritize patching or mitigation strategies as soon as possible.
