CVE-2023-44018
Published: 27 September 2023
Summary
CVE-2023-44018 is a critical-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tendacn Ac10U Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 9.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Tenda AC10U v1.0 running firmware US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01 contains a stack-based buffer overflow in the add_white_node function triggered by the domain parameter. The flaw is tracked as CVE-2023-44018 with CVSS 9.8 and is associated with CWE-119 and CWE-121.
An unauthenticated attacker can send a crafted HTTP request over the network to overflow the stack, leading to arbitrary code execution or denial of service that fully compromises confidentiality, integrity, and availability of the device. No vendor advisory or patch information is supplied in the available references, which consist solely of proof-of-concept details hosted on GitHub. The EPSS score has remained flat at 0.0584 with no material increase since 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.
