CVE-2024-31152
Published: 30 October 2024
Summary
CVE-2024-31152 is a medium-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Level1 Wbr-6012 Firmware. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 6.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The LevelOne WBR-6012 router with firmware R0.40e6 is affected by CVE-2024-31152, an improper resource allocation flaw in the device's web application. The issue, also described under CWE-400 and CWE-770, allows uncontrolled consumption of resources when the web interface processes certain inputs, and carries a CVSS 3.1 score of 5.3.
An unauthenticated attacker with network access can send a series of crafted HTTP requests that exhaust resources and force the router to reboot, producing a denial-of-service condition that interrupts network connectivity. No authentication or user interaction is required, and the attack can be launched remotely over the network.
Public references point to detailed analysis from Cisco Talos but do not include vendor-supplied patches or configuration workarounds in the available information. The associated EPSS score has remained steady at 0.0965 with no material increase observed after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
Planning and coordination of security activities (scans, tests, maintenance) directly imposes scheduling and throttling that prevents those activities from producing uncontrolled resource consumption.
Performance metrics and monitoring inherently track resource consumption patterns, making uncontrolled consumption easier to detect and mitigate.
Terminating idle connections bounds resource consumption that would otherwise allow uncontrolled accumulation of open sessions.
