CVE-2022-45506: n/a in n/a
Tenda W30E v1.0.1.25(633) was discovered to contain a command injection vulnerability via the fileNameMit parameter at /goform/delFileName.
AI Analysis
Technical Summary
CVE-2022-45506 is a critical command injection vulnerability identified in the Tenda W30E router firmware version 1.0.1.25(633). The vulnerability exists in the handling of the 'fileNameMit' parameter within the '/goform/delFileName' endpoint. This parameter is susceptible to unsanitized input, allowing an attacker to inject arbitrary operating system commands. Since the vulnerability is remotely exploitable over the network without requiring any authentication or user interaction, an attacker can execute arbitrary commands with the privileges of the web server process, potentially leading to full system compromise. The CVSS v3.1 base score of 9.8 reflects the high severity, with metrics indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality (C:H), integrity (I:H), and availability (A:H). The underlying weakness corresponds to CWE-78 (Improper Neutralization of Special Elements used in an OS Command), a common and dangerous class of vulnerabilities. Although no known exploits have been reported in the wild as of the publication date, the ease of exploitation and critical impact make this a significant threat to affected devices. The lack of vendor or product details beyond the Tenda W30E model limits the scope of affected versions, but the vulnerability is specific to this router firmware version. The absence of available patches or mitigation links suggests that affected users must rely on other protective measures until an official fix is released.
Potential Impact
For European organizations, this vulnerability poses a substantial risk, especially for enterprises and service providers using Tenda W30E routers in their network infrastructure. Successful exploitation can lead to complete compromise of the router, enabling attackers to intercept, modify, or disrupt network traffic, deploy further malware, or pivot into internal networks. This can result in data breaches, loss of service availability, and potential exposure of sensitive information. Given the critical nature of the vulnerability and the lack of authentication requirements, attackers can remotely exploit vulnerable devices en masse, potentially leading to large-scale network disruptions. The impact is particularly severe for organizations relying on these routers for perimeter security or remote access. Additionally, compromised routers can be leveraged to launch attacks against other targets, amplifying the threat landscape. The vulnerability also threatens the integrity and availability of network services, which can affect critical infrastructure sectors prevalent in Europe, such as finance, healthcare, and manufacturing. The absence of known exploits in the wild does not diminish the urgency, as public disclosure increases the likelihood of exploitation attempts.
Mitigation Recommendations
1. Immediate Network Segmentation: Isolate Tenda W30E devices from critical network segments to limit potential lateral movement if compromised. 2. Disable Remote Management: If remote management interfaces are enabled on these routers, disable them to reduce exposure to external attackers. 3. Monitor Network Traffic: Implement intrusion detection systems (IDS) and anomaly detection to identify unusual command injection attempts targeting the '/goform/delFileName' endpoint or suspicious outbound connections from routers. 4. Apply Vendor Updates: Continuously monitor Tenda's official channels for firmware updates addressing this vulnerability and apply patches promptly once available. 5. Replace Vulnerable Devices: For high-security environments, consider replacing Tenda W30E routers with devices from vendors with a stronger security track record and active patch management. 6. Harden Router Configuration: Change default credentials, disable unnecessary services, and restrict access to management interfaces to trusted IP addresses only. 7. Incident Response Preparedness: Develop and test incident response plans specifically for network device compromises to enable rapid containment and remediation. 8. Vendor Engagement: Engage with Tenda support to request timelines for patches and inquire about interim mitigations or workarounds.
