CVSS: 8.8EPSS: 86%CPEs: 6EXPL: 0CVE-2020-8864 – D-Link Multiple Routers HNAP strncmp Incorrect Comparison Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-8864
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-867, DIR-878, and DIR-882 routers with firmware 1.10B04. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper handling of empty passwords. An attacker can leverage this vulnerability to execute arbitrary code on the router. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10157 https://www.zerodayinitiative.com/advisories/ZDI-20-268 • CWE-697: Incorrect Comparison •

An issue was discovered on D-Link DIR-878 1.12B01 devices. Because strncpy is misused, there is a stack-based buffer overflow vulnerability that does not require authentication via the HNAP_AUTH HTTP header. Se ha descubierto un problema en dispositivos D-Link DIR-878 1.12B01. Debido a que strncpy se emplea de manera incorrecta, hay una vulnerabilidad de desbordamiento de búfer basada en pila que no requiere autenticación mediante la cabecera HNAP_AUTH HTTP. • https://github.com/WhooAmii/whooamii.github.io/blob/master/2018/DIR-878/overflow1.md https://github.com/WhooAmii/whooamii.github.io/blob/master/2018/DIR-878/overflow2.md • CWE-306: Missing Authentication for Critical Function CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-8316
An issue was discovered on D-Link DIR-878 devices with firmware 1.12A1. This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 POST request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body for the SetWebFilterSettings API function, as demonstrated by shell metacharacters in the WebFilterURLs field.
