CVSS: 7.2EPSS: 1%CPEs: 2EXPL: 1CVE-2023-31742
https://notcve.org/view.php?id=CVE-2023-31742
There is a command injection vulnerability in the Linksys WRT54GL router with firmware version 4.30.18.006. If an attacker gains web management privileges, they can inject commands into the post request parameters wl_ant, wl_rate, WL_atten_ctl, ttcp_num, ttcp_size in the httpd s Start_EPI() function, thereby gaining shell privileges. • http://linksys.com https://github.com/D2y6p/CVE/blob/main/Linksys/CVE-2023-31742/Linksys_WRT54GL_RCE.pdf • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 3CVE-2022-43972 – Null pointer dereference in Linksys WRT54GL
https://notcve.org/view.php?id=CVE-2022-43972
A null pointer dereference vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A null pointer dereference in the soap_action function within the upnp binary can be triggered by an unauthenticated attacker via a malicious POST request invoking the AddPortMapping action. Existe una vulnerabilidad de desreferencia de puntero nulo en el router Linksys WRT54GL Wireless-G Broadband con firmware <= 4.30.18.006. Un atacante no autenticado puede desencadenar una desreferencia de puntero nulo en la función SOAP_action dentro del binario upnp a través de una solicitud POST maliciosa que invoca la acción AddPortMapping. • https://youtu.be/73-1lhvJPNg https://youtu.be/RfWVYCUBNZ0 https://youtu.be/TeWAmZaKQ_w • CWE-476: NULL Pointer Dereference •
CVSS: 7.2EPSS: 0%CPEs: 2EXPL: 3CVE-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 •
CVSS: 7.2EPSS: 0%CPEs: 2EXPL: 3CVE-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') •
