CVE-2025-10779
Published: 22 September 2025
Summary
CVE-2025-10779 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dcs-935L Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 42.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SA-22 (Unsupported System Components) and SC-7 (Boundary Protection).
Deeper analysis
CVE-2025-10779 is a stack-based buffer overflow vulnerability affecting D-Link DCS-935L firmware versions up to 1.13.01. The flaw exists in the sub_402280 function within the /HNAP1/ file and is triggered by manipulating the HNAP_AUTH/SOAPAction argument. It is associated with CWEs-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), CWE-121 (Stack-based Buffer Overflow), and CWE-787 (Out-of-bounds Write).
The vulnerability enables remote exploitation over the network by an attacker possessing low privileges, with low attack complexity and no requirement for user interaction. Per its CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), successful exploitation grants high impacts to confidentiality, integrity, and availability, potentially allowing arbitrary code execution. A public exploit is available for use.
Advisories note that the vulnerability exclusively impacts products no longer supported by the maintainer, with no patches available. Relevant references include detailed analyses on GitHub (scanleale/IOT_sec repositories) and VulDB entries (ctiid.325135, id.325135, submit.653690), which document the issue but do not specify mitigations beyond device replacement or isolation.
An exploit has been publicly disclosed, increasing the risk for exposed, end-of-support devices.

Prohibits or applies safeguards to unsupported end-of-life components like the D-Link DCS-935L with no patches available for this buffer overflow vulnerability.
Provides memory protections such as DEP, ASLR, and stack canaries to prevent exploitation of stack-based buffer overflows triggered by malformed HNAP_AUTH/SOAPAction inputs.
Enforces boundary protection to block remote network access to the vulnerable /HNAP1/ endpoint, mitigating low-privilege remote exploitation.
