Summary
CVE-2024-7441 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Vivotek Sd9364 Firmware. Its CVSS base score is 8.7 (High).
Operationally, ranked in the top 6.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-7441 is a stack-based buffer overflow vulnerability, also referenced under CWE-121 and CWE-119, that affects the read function in the httpd component of the Vivotek SD9364 network camera running firmware VVTK-0103f. The flaw is triggered by improper handling of the Content-Length argument supplied to the server and has been classified as critical with a CVSS 4.0 score of 8.7. The issue was reported against a release tree that the vendor has confirmed is end-of-life and no longer supported.
An authenticated remote attacker can supply a crafted Content-Length value over the network to overflow the stack buffer, resulting in high impact to confidentiality, integrity, and availability. Public exploit code has been disclosed, enabling potential remote code execution or denial-of-service conditions on affected devices.
Vendor contact early in the disclosure process confirmed that the affected firmware branch has reached end-of-life, so no patches or updates are available; the references on VulDB and the accompanying technical write-up reiterate that only unsupported products are impacted. The associated EPSS score has remained flat at 0.1136 since publication, indicating no material increase in observed exploitation interest.

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.
