Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.5th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

Kepler Wallpaper Script version 1.1 is affected by CVE-2019-25576, an SQL injection vulnerability (CWE-89) in the category parameter. This flaw enables unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code, such as URL-encoded SQL UNION statements, into GET requests sent to the category endpoint. The vulnerability has a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low attack complexity over the network.

Unauthenticated remote attackers can exploit this vulnerability without privileges or user interaction. By crafting malicious GET requests to the category endpoint, they can extract sensitive database information, including usernames, database names, and MySQL version details, potentially leading to further compromise depending on the database contents and configuration.

Advisories and resources, including those from VulnCheck and Exploit-DB (exploit 46207), document the issue with proof-of-concept exploits. The original software is available via CodeClerks, and a live instance exists at keplerwallpapers.online, but no specific patches or mitigation steps are detailed in the provided references. Security practitioners should scan for and remove or update instances of Kepler Wallpaper Script 1.1.
