Summary

CVE-2019-25339 is a medium-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Apple (inferred from references). Its CVSS base score is 6.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 10.0th percentile by exploit likelihood (below the median); 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 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2019-25339 is a denial of service vulnerability in GHIA CamIP version 1.2 for iOS, specifically within the password input field. Attackers can trigger an application crash by pasting a 33-character buffer of repeated characters into this field on iOS devices. The vulnerability is associated with CWE-121 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). It was published on 2026-02-12.

The vulnerability can be exploited by any network-accessible attacker with no required privileges or user interaction. Successful exploitation leads to a crash of the GHIA CamIP application, resulting in a denial of service condition for affected users.

Advisories and related resources include the GHIA CamIP app listing on the Apple App Store, a proof-of-concept exploit on Exploit-DB (ID 47721), and a VulnCheck advisory detailing the password denial of service issue. No specific patch or mitigation details are provided in the core vulnerability data.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly validates inputs to the password field to reject oversized or malformed buffers like the 33-character repeated string that triggers the application crash.

prevent

Enforces input restrictions such as maximum length and allowed characters in the password field to block the buffer overflow exploit.

prevent

Protects against denial-of-service events specifically targeting the vulnerable password input field with crafted pastes.
