CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2021-34863 – D-Link DAP-2020 webproc var:page Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34863
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2020 1.01rc001 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the var:page parameter provided to the webproc endpoint. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10201 https://www.zerodayinitiative.com/advisories/ZDI-21-979 • CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2021-34861
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2020 1.01rc001 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the webproc endpoint, which listens on TCP port 80 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10201 https://www.zerodayinitiative.com/advisories/ZDI-21-977 • CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2021-27248
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2020 v1.01rc001 Wi-Fi access points. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of CGI scripts. When parsing the getpage parameter, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10201 https://www.zerodayinitiative.com/advisories/ZDI-21-203 • CWE-121: Stack-based Buffer Overflow •
