Title
WDR201A WiFi Extender Stack-Based Buffer Overflow via firewall.cgi
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains a stack-based buffer overflow vulnerability in the firewall.cgi and makeRequest.cgi binaries that allows unauthenticated attackers to overwrite the saved return address by sending a POST request with a Content-Length header exceeding 512 bytes. Attackers can exploit insufficient length validation in the fgets() call to achieve arbitrary code execution through return-oriented programming or return-to-libc techniques.
Severity ?

Title
WDR201A WiFi Extender OS Command Injection via firewall.cgi
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the firewall.cgi binary across five request handlers that apply insufficient input validation. Attackers can inject arbitrary shell commands through vulnerable parameters like websURLFilter, websHostFilter, portForward, singlePortForward, and ipportFilter using subshell syntax or unfiltered parameters, with payloads persisting in NVRAM and re-executing on every subsequent firewall.cgi request.

Title
WDR201A WiFi Extender OS Command Injection via adm.cgi (reboot_time)
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the adm.cgi binary's reboot_time function that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the reboot_time POST parameter. Attackers can send a crafted request with shell metacharacters in the reboot_time parameter when reboot_enabled=1 to achieve remote code execution.

Title
WDR201A WiFi Extender OS Command Injection via makeRequest.cgi
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the makeRequest.cgi binary that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the set_time or StartSniffer functions. Attackers can craft a POST request with specially crafted ampersand-delimited parameters to bypass input sanitization and execute commands with a maximum length of 31 bytes through the date command or channel parameter processing.

Title
WDR201A WiFi Extender OS Command Injection via internet.cgi
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the internet.cgi binary that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the gateway POST parameter. Attackers can exploit unsanitized parameter concatenation in the set_add_routing function to inject shell commands that are executed via popen() with partial output reflected in the HTTP response.

VLAI?
Title
WDR201A WiFi Extender OS Command Injection via wireless.cgi
Summary
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the wireless.cgi binary that allow unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the sz11gChannel or PIN POST parameters. Attackers can exploit unsanitized parameter handling in the set_wifi_basic and set_wifi_do_wps functions to achieve remote code execution without authentication.
Severity ?
