CVE-2025-5875
Published: 09 June 2025
Summary
CVE-2025-5875 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tp-Link Tl-Ipc544Ep-W4 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 21.5% 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 critical buffer overflow vulnerability, tracked as CVE-2025-5875 and assigned CWE-119 and CWE-120, affects the TP-Link TL-IPC544EP-W4 camera running firmware version 1.0.9 Build 240428 Rel 69493n. The flaw resides in the sub_69064 function within /bin/main, where unsanitized input supplied to the "text" argument can trigger an out-of-bounds write.
An authenticated remote attacker can send a crafted request over the network to overflow the buffer, leading to arbitrary code execution with high impact on confidentiality, integrity, and availability. The CVSS 4.0 vector reflects network attack reachability, low complexity, and no required user interaction, and a functional exploit has already been made public.
The vendor was notified prior to disclosure but has not issued a response or patch. Public references, including a detailed technical write-up and VulDB entries, confirm the issue but provide no mitigation guidance beyond the general recommendation to restrict network access to the device until a firmware update becomes available. The associated EPSS score has remained flat at 0.0110 with no material increase since publication.

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.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
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.
