CVE-2024-50319 is a high-severity Infinite Loop (CWE-835) vulnerability in Ivanti Avalanche. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-2 (Flaw Remediation) — 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.
An infinite loop vulnerability tracked as CVE-2024-50319 affects Ivanti Avalanche versions prior to 6.4.6. The flaw, assigned CWE-835, resides in a network-accessible component and carries a CVSS 3.1 base score of 7.5 reflecting high availability impact with no requirements for authentication or user interaction.
A remote unauthenticated attacker can send crafted requests over the network to trigger the infinite loop, resulting in denial of service that renders the application unavailable while leaving confidentiality and integrity unaffected.
The vendor advisory at the referenced Ivanti forum URL addresses this issue among multiple CVEs disclosed in the Q4 2024 release and directs customers to upgrade to Avalanche 6.4.6 to eliminate the loop condition. The associated EPSS score has remained flat at 0.0783 with no observed increase since publication.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover unreachable loop exit conditions through static analysis, fuzzing, or execution tracing.
Flaw remediation processes identify and correct infinite-loop defects reported from testing or operations.
Requiring documented development processes and secure coding standards reduces introduction of loops whose termination conditions are unreachable.

Security testing can uncover infinite-loop conditions before release.
Secure development life cycle mandates practices that can detect and prevent infinite-loop defects.
Application security requirements can specify loop-termination rules, indirectly reducing the weakness.
Secure coding standards directly address loop termination and prevent infinite loops.
Secure architecture principles encourage designs that avoid unreachable exit conditions.
Change management can require review of loop logic when code is modified.
