Source: CVE Program / CVE List V5
Vulnerability Description
On certain TOTOLINK Realtek SDK based routers, the CAPTCHA text can be retrieved via an {"topicurl":"setting/getSanvas"} POST to the boafrm/formLogin URI, leading to a CAPTCHA bypass. (Also, the CAPTCHA text is not needed once the attacker has determined valid credentials. The attacker can perform router actions via HTTP requests with Basic Authentication.) This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, and N100RE through 3.4.0.

II. Public POCs for CVE-2019-19825

# POC Description Source Link Shenlong Link
1 On certain TOTOLINK Realtek SDK based routers, the CAPTCHA text can be retrieved via a POST request to the boafrm/formLogin URI with the JSON payload {"topicurl":"setting/getSanvas"}. This allows an unauthenticated attacker to bypass CAPTCHA verification, gaining unauthorized access to restricted functions. Once valid credentials are known or brute-forced, an attacker can fully control the device using HTTP requests and Basic Authentication. Affected router models include A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, N100RE through 3.4.0, and other Realtek SDK-derived devices. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2019/CVE-2019-19825.yaml POC Details
