An issue was discovered in prog.cgi on D-Link DIR-878 1.30B08 devices. Because strcat is misused, there is a stack-based buffer overflow that does not require authentication. Se detectó un problema en el archivo prog.cgi en dispositivos D-Link DIR-878 versión 1.30B08. Debido al uso inapropiado de strcat, se presenta un desbordamiento de búfer en la región stack de la memoria que no requiere autenticación. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10217 https://www.dlink.com/en/security-bulletin • CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2020-15633 – D-Link Multiple Routers HNAP GetCAPTCHAsetting Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-15633
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 1.20B10_BETA. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP requests. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10186 https://www.zerodayinitiative.com/advisories/ZDI-20-881 • CWE-288: Authentication Bypass Using an Alternate Path or Channel •
