Description

A remote attacker can conduct a cross-site request forgery (CSRF) attack on OPTILINK OP-XT71000N Hardware Version: V2.2 , Firmware Version: OP_V3.3.1-191028. The vulnerability is due to insufficient CSRF protections for the "mgm_config_file.asp" because of which attacker can create a crafted "csrf form" which sends " malicious xml data" to "/boaform/admin/formMgmConfigUpload". the exploit allows attacker to "gain full privileges" and to "fully compromise of router & network".

Technical Analysis

CVE-2020-23585 is a high-severity vulnerability affecting the OPTILINK OP-XT71000N router, specifically hardware version V2.2 and firmware version OP_V3.3.1-191028. The root cause of the vulnerability is insufficient Cross-Site Request Forgery (CSRF) protections on the management configuration file interface, specifically the "mgm_config_file.asp" page. An attacker can craft a malicious CSRF form that submits specially crafted XML data to the endpoint "/boaform/admin/formMgmConfigUpload". This exploit allows the attacker to bypass authentication and authorization controls, effectively gaining full administrative privileges on the router. Once compromised, the attacker can fully control the router and potentially the connected network, leading to a complete compromise of network confidentiality, integrity, and availability. The CVSS v3.1 base score is 8.8, reflecting the vulnerability's ease of exploitation (network vector, low attack complexity, no privileges required, but user interaction needed) and its critical impact on confidentiality, integrity, and availability. Although no known public exploits have been reported in the wild, the vulnerability presents a significant risk due to the router's role as a network gateway device, which is a high-value target for attackers aiming to intercept, manipulate, or disrupt network traffic. The vulnerability is classified under CWE-352, which corresponds to CSRF attacks, indicating a failure to implement proper anti-CSRF tokens or similar protections in the affected firmware version. The lack of vendor or product information beyond the router model suggests limited public documentation, which may complicate detection and mitigation efforts for some organizations.

Potential Impact

For European organizations, the impact of this vulnerability can be severe. The OPTILINK OP-XT71000N router is typically deployed in enterprise or service provider environments, where it acts as a critical network infrastructure component. Successful exploitation can lead to unauthorized administrative access, allowing attackers to alter network configurations, intercept sensitive communications, deploy malware, or create persistent backdoors. This can result in data breaches, service disruptions, and loss of trust. Given the router's position at the network perimeter, a compromised device can serve as a pivot point for lateral movement within corporate networks, increasing the risk of widespread compromise. Additionally, critical sectors such as telecommunications, finance, and government agencies in Europe that rely on this hardware could face operational disruptions and regulatory consequences under GDPR if personal data is exposed. The requirement for user interaction (e.g., visiting a malicious website) means that phishing or social engineering campaigns could be leveraged to trigger the exploit, increasing the attack surface. The absence of known public exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop or share exploits privately. Overall, the vulnerability poses a high risk to network security and operational continuity for affected European organizations.

Mitigation Recommendations

1. Immediate firmware upgrade: Organizations should verify if OPTILINK has released a patched firmware version addressing CVE-2020-23585 and apply it promptly. 2. Network segmentation: Isolate the management interface of the OP-XT71000N router from general user networks and restrict access to trusted administrative hosts only, using VLANs or firewall rules. 3. Implement strict access controls: Enforce strong authentication mechanisms (e.g., multi-factor authentication) for router management interfaces and disable remote management if not required. 4. Monitor network traffic: Deploy intrusion detection/prevention systems (IDS/IPS) to detect anomalous POST requests to "/boaform/admin/formMgmConfigUpload" or unusual XML payloads indicative of exploitation attempts. 5. User awareness training: Educate users about the risks of phishing and social engineering that could trigger CSRF attacks, emphasizing caution when clicking on unknown links or visiting untrusted websites. 6. Web application firewall (WAF): If feasible, deploy a WAF to filter and block malicious CSRF attempts targeting the router's management endpoints. 7. Regular security audits: Conduct periodic vulnerability assessments and penetration tests focusing on network infrastructure devices to identify and remediate similar weaknesses. 8. Disable unnecessary services: Turn off any unused web management interfaces or services on the router to reduce the attack surface. These mitigations go beyond generic advice by focusing on network architecture changes, user behavior, and proactive monitoring tailored to the specific vulnerability and device.
