Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

SI-10 directly enforces proper validation of information inputs to prevent buffer overflows from improper input handling in Progress LoadMaster.

SI-16 Memory Protection good match

prevent

SI-16 implements memory protection safeguards that mitigate buffer overflow exploits by preventing unauthorized memory access or manipulation.

SI-2 Flaw Remediation good match

prevent

SI-2 ensures timely identification, reporting, and patching of flaws like CVE-2025-1758 as detailed in Progress LoadMaster security updates.

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.

Deeper analysisAI

CVE-2025-1758 is an Improper Input Validation vulnerability in Progress LoadMaster that enables a Buffer Overflow, classified under CWE-121. It affects LoadMaster versions 7.2.40.0 and above, all versions of ECS, and Multi-Tenancy versions 7.1.35.4 and above. The vulnerability carries a CVSS v3.1 base score of 4.3 (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L), indicating a moderate severity with primary impact on availability.

An attacker on an adjacent network (AV:A) can exploit this vulnerability with low complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:N). Exploitation leads to a buffer overflow, resulting in low-impact availability disruption (A:L) with no effects on confidentiality or integrity and unchanged scope (S:U), such as causing partial denial of service on the affected components.

Progress advisories detail mitigations in the security updates section of the LoadMaster 7.2.61.1 release notes, available at https://docs.progress.com/bundle/release-notes_loadmaster-7-2-61-1/page/Security-Updates.html. Practitioners should review these notes for patching instructions and upgrade to addressed versions to remediate the issue.
