The vulnerability identified as CVE-2025-60341 affects the Tenda AC6 V2.0 router firmware version 15.03.06.50. It is a stack-based buffer overflow (CWE-121) occurring in the fast_setting_wifi_set function when processing the ssid parameter. This function likely handles Wi-Fi configuration settings, and improper input validation or bounds checking allows an attacker to overflow the stack by sending a specially crafted SSID value. Exploiting this flaw does not require any privileges or user interaction and can be performed remotely over the network, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The primary impact is a Denial of Service (DoS), where the router crashes or becomes unresponsive, disrupting network connectivity. Although no public exploits have been reported yet, the vulnerability's characteristics suggest it could be weaponized to cause widespread outages, especially in environments relying on these routers for internet access or internal networking. The absence of a patch link indicates that a fix may not yet be available, increasing the urgency for mitigation. The vulnerability's high CVSS score of 7.5 reflects its significant impact on availability and ease of exploitation.

For European organizations, this vulnerability poses a risk of network disruption due to router crashes caused by maliciously crafted SSID inputs. Organizations using Tenda AC6 routers in offices, retail locations, or critical infrastructure could experience denial of service, leading to loss of internet connectivity, interruption of business operations, and potential cascading effects on dependent systems. The impact is particularly severe for sectors requiring high availability, such as finance, healthcare, and public services. Additionally, the lack of authentication and user interaction requirements means attackers can exploit this remotely, increasing the threat surface. While confidentiality and integrity are not directly impacted, the availability loss can indirectly affect operational security and service delivery. The vulnerability could also be leveraged as part of a larger attack chain to distract or delay incident response.

Immediate mitigation should focus on network-level controls to detect and block malformed SSID inputs targeting the fast_setting_wifi_set function. Organizations should implement intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection tuned for unusual Wi-Fi configuration traffic. Segmentation of network management interfaces and restricting access to router configuration endpoints can reduce exposure. Monitoring router logs for crashes or unusual behavior is critical for early detection. Since no patch is currently available, organizations should consider replacing vulnerable Tenda AC6 devices with updated hardware or firmware versions once released. Vendors and users should prioritize firmware updates as soon as they become available. Additionally, organizations should maintain an inventory of affected devices and apply compensating controls such as network access control (NAC) to limit unauthorized devices and traffic.
