CVE-2020-23586: n/a in n/a
A vulnerability found in OPTILINK OP-XT71000N Hardware Version: V2.2 , Firmware Version: OP_V3.3.1-191028 allows an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack to Add Network Traffic Control Type Rule.
AI Analysis
Technical Summary
CVE-2020-23586 is a security vulnerability identified in the OPTILINK OP-XT71000N device, specifically in hardware version V2.2 running firmware version OP_V3.3.1-191028. The vulnerability is a Cross-Site Request Forgery (CSRF) flaw categorized under CWE-352. It allows an unauthenticated remote attacker to add a Network Traffic Control Type Rule on the device without requiring prior authentication. The attack exploits the device's web interface by tricking an authenticated user into submitting a malicious request unknowingly, which results in unauthorized modification of network traffic control settings. The vulnerability has a CVSS v3.1 base score of 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be launched remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity, as the attacker can alter network traffic control rules, potentially affecting network behavior, but there is no direct impact on confidentiality or availability. No known exploits have been reported in the wild, and no patches or vendor advisories are currently available. The vulnerability affects a specific hardware and firmware combination, limiting the scope of affected systems. Since the product and vendor details are sparse, it is understood that the OPTILINK OP-XT71000N is a network device, likely used in enterprise or service provider environments for traffic management or routing purposes.
Potential Impact
For European organizations using the OPTILINK OP-XT71000N device with the specified firmware, this vulnerability could allow attackers to manipulate network traffic control rules remotely without authentication. This manipulation could lead to unauthorized traffic shaping, blocking, or prioritization, potentially degrading network performance or enabling further attacks such as traffic interception or denial of service on critical network segments. While the vulnerability does not directly compromise data confidentiality or availability, the integrity of network traffic management is affected, which can disrupt business operations or expose the network to additional threats. Organizations in sectors relying heavily on network performance and security—such as telecommunications, finance, and critical infrastructure—may face operational risks. The requirement for user interaction reduces the likelihood of automated exploitation but does not eliminate risk, especially in environments where users frequently access the device's management interface. The absence of known exploits and patches suggests a window of exposure, emphasizing the need for proactive mitigation.
Mitigation Recommendations
1. Restrict access to the device's management interface by implementing network segmentation and firewall rules to limit access only to trusted administrative hosts. 2. Disable or restrict web interface access from untrusted networks, especially the internet-facing interfaces. 3. Employ browser security measures such as disabling or limiting the use of scripts and cross-site requests when accessing the device interface. 4. Educate users and administrators about the risks of CSRF attacks and encourage cautious behavior when interacting with device management portals, including avoiding clicking on suspicious links or visiting untrusted websites while logged into the device interface. 5. Monitor network traffic and device logs for unusual changes in traffic control rules or unexpected configuration changes. 6. Regularly check for firmware updates or vendor advisories addressing this vulnerability and apply patches promptly once available. 7. Consider deploying Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) capable of detecting and blocking CSRF attack patterns targeting the device's management interface. 8. If possible, implement multi-factor authentication and session management controls to reduce the risk of unauthorized configuration changes.
