Summary

CVE-2019-25358 is a high-severity Assumed-Immutable Data is Stored in Writable Memory (CWE-1282) vulnerability in Sourceforge (inferred from references). 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 31th 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.

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

CVE-2019-25358 is a denial of service vulnerability affecting FileOptimizer version 14.00.2524. The issue arises from improper handling of the TempDirectory parameter in the FileOptimizer32.ini configuration file, where attackers can overwrite it with a 5000-character buffer. This manipulation causes the application to crash when the options dialog is opened. The vulnerability is associated with CWE-1282 and has 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).

Any unauthenticated attacker can exploit this vulnerability remotely with low complexity and no user interaction required. By crafting a malicious FileOptimizer32.ini file with an oversized TempDirectory value, the attacker triggers a crash upon the victim opening the options in the affected application, resulting in denial of service.

References include the SourceForge project pages for FileOptimizer, an Exploit-DB proof-of-concept (exploit 47586), and a Vulncheck advisory detailing the denial of service issue. These resources provide additional technical details, but no specific patch or mitigation steps are outlined in the available information. Security practitioners should review the advisories and avoid using the vulnerable version 14.00.2524.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly addresses the vulnerability by requiring validation of configuration file inputs like the oversized TempDirectory parameter to prevent application crashes.

prevent

Provides specific protections against denial-of-service events such as the buffer-induced crash from manipulated FileOptimizer32.ini files.

prevent

Ensures graceful error handling for invalid configuration inputs, mitigating crashes without diagnostic output that could exacerbate the denial of service.

prevents

Secure development life cycle mandates hardware-enforced immutability or protected storage for bootloaders and device identifiers.

prevents

Secure system architecture principles require hardware write-protection or one-time-programmable memory for immutable data.

prevents

Secure coding practices can avoid storing immutable data in writable memory but do not address hardware-level protection.

mitigates

Change management can restrict field updates to immutable data but does not enforce the underlying storage design.

mitigates

Configuration management enforces immutable firmware and write-once settings, directly preventing unauthorized reprogramming of assumed-immutable data.
