Summary

CVE-2019-25552 is a high-severity Use of Password Hash Instead of Password for Authentication (CWE-836) vulnerability in Cewe Photo Show. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 32th 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 map to SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2019-25552 is a denial of service vulnerability affecting CEWE PHOTO SHOW version 6.4.3. The issue arises from the application's failure to properly handle an excessively long buffer submitted to the password field during the upload process, allowing attackers to crash the program by pasting a large string of repeated characters into the input.

The vulnerability can be exploited by any network-accessible attacker with no privileges required and low complexity, as reflected in its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and associated CWE-836. Exploitation leads to a complete application crash, resulting in denial of service for the affected instance.

Advisories and references, including those from VulnCheck detailing the denial of service via the password field, an Exploit-DB entry (46861), and the vendor site at cewe-photoworld.com, provide further details but no specific patch or mitigation guidance is outlined in the available information.

A proof-of-concept exploit is publicly available on Exploit-DB, confirming practical exploitability published on 2026-03-21.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Buffer overflow in password field directly enables application crash via exploitation (T1499.004).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly mandates input validation at the password field to reject excessively long buffers, preventing the DoS crash from mishandled input.

prevent

Enforces input restrictions like maximum length at the password field during upload, blocking oversized strings that trigger the crash.

prevent

Implements protections to limit effects of denial-of-service events such as the application crash from excessive password buffer input.

Proper authentication mechanisms require passwords (not pre-hashed values) to be supplied by the claimant and verified server-side.

degrades

Directly requires secure handling and protection of authentication credentials, preventing storage or comparison of password hashes as if they were passwords.

degrades

Mandates secure authentication mechanisms that preclude the flawed practice of treating password hashes as authenticators.

degrades

Requires proper cryptographic practices for protecting passwords, indirectly mitigating misuse of hashes in authentication.

prevents

Secure coding guidance can prevent this implementation error but does not address the control's broader intent.
