CVE-2022-43973 – Arbitrary code execution in Linksys WRT54GL
https://notcve.org/view.php?id=CVE-2022-43973
An arbitrary code execution vulnerability exisits in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. The Check_TSSI function within the httpd binary uses unvalidated user input in the construction of a system command. An authenticated attacker with administrator privileges can leverage this vulnerability over the network via a malicious POST request to /apply.cgi to execute arbitrary commands on the underlying Linux operating system as root. Existe una vulnerabilidad de ejecución de código arbitrario en el router Linksys WRT54GL Wireless-G Broadband con firmware <= 4.30.18.006. La función Check_TSSI dentro del binario httpd utiliza entradas de usuario no validadas en la construcción de un comando del sistema. • https://youtu.be/73-1lhvJPNg https://youtu.be/RfWVYCUBNZ0 https://youtu.be/TeWAmZaKQ_w • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2022-43970 – Buffer overflow in Linksys WRT54GL
https://notcve.org/view.php?id=CVE-2022-43970
A buffer overflow vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A stack-based buffer overflow in the Start_EPI function within the httpd binary allows an authenticated attacker with administrator privileges to execute arbitrary commands on the underlying Linux operating system as root. This vulnerablity can be triggered over the network via a malicious POST request to /apply.cgi. Existe una vulnerabilidad de desbordamiento del búfer en el router Linksys WRT54GL Wireless-G Broadband con firmware <= 4.30.18.006. Un desbordamiento de búfer en la región stack de la memoria en la función Start_EPI dentro del binario httpd permite a un atacante autenticado con privilegios de administrador ejecutar comandos arbitrarios en el sistema operativo Linux subyacente como root. • https://youtu.be/73-1lhvJPNg https://youtu.be/RfWVYCUBNZ0 https://youtu.be/TeWAmZaKQ_w • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
