CVE-2025-5228
Published: 27 May 2025
Summary
CVE-2025-5228 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Di-8100 Firmware. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation of Remote Services (T1210); ranked in the top 17.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A vulnerability classified as critical was found in D-Link DI-8100 firmware up to 20250523. It resides in the httpd_get_parm function of the /login.cgi file within the jhttpd component, where improper handling of the notify argument triggers a stack-based buffer overflow, corresponding to CWE-119 and CWE-121.
The flaw can be exploited by unauthenticated attackers located on the local network, who may leverage a publicly disclosed proof-of-concept to achieve high impact on confidentiality, integrity, and availability without requiring user interaction. The CVSS 4.0 vector reflects an adjacent-network attack with low complexity and no privileges needed.
No vendor advisory or patch details are provided in the references, which include a GitHub report, VulDB entries, and the D-Link site. The EPSS score remains flat at 0.0162 with no observed rise after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
