A stack-based buffer overflow vulnerability exists in the web interface Radio Scheduling functionality of the Tp-Link AC1350 Wireless MU-MIMO Gigabit Access Point (EAP225 V3) v5.1.0 Build 20220926. This vulnerability allows specially crafted HTTP requests to lead to remote code execution. Specifically, an attacker can make an authenticated HTTP request to trigger this vulnerability. The overflow occurs via the `action` parameter at offset `0x422448` of the `httpd` binary shipped with v5.0.4 Build 20220216 of the EAP115.
The CVSS score for this vulnerability is 7.2, classified as high severity, indicating significant risk to organizations. The attack vector is network-based, requiring high privileges to execute the exploit. Given the potential for remote code execution, organizations should prioritize patching immediately.
Risk to organizations includes unauthorized access and control over affected devices, which could lead to further exploits within the network. It is imperative to assess the exposure of these devices and ensure that proper security measures are in place.
Currently, there are no known exploits or public proof-of-concept (PoC) available for this vulnerability, reducing immediate exploitation risk. However, cybersecurity teams should remain vigilant as new threats could emerge.
Vulnerability Details
The vulnerability is specifically identified as CWE-121 (Stack-based Buffer Overflow) and CWE-787 (Out-of-bounds Write). The affected products include the Tp-Link EAP225 firmware version 5.1.0 and EAP115 firmware version 5.0.4. It was published on April 9, 2024. The potential impacts include high confidentiality, integrity, and availability risks.
Technical Analysis
The root cause of this vulnerability is the improper handling of input via the web interface, leading to a stack-based buffer overflow. The attack vector is network-based, meaning an attacker can exploit it remotely without being physically present. The attack complexity is low, as the exploit does not require any special conditions to be met beyond having high privileges. User interaction is not required, making this vulnerability particularly concerning.
The impacts on confidentiality, integrity, and availability are high, as attackers may gain unauthorized access to sensitive data, modify system configurations, or disrupt service availability.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant. Organizations using affected Tp-Link devices may face severe impacts if exploited by attackers. The blast radius potential is considerable, as a successful exploit could compromise entire networks. Given the vulnerability's high CVSS score and the lack of known exploits, organizations should assess their security posture and prioritize patching as part of their response strategy.
