DescriptionCVE.org

A vulnerability was determined in Open5GS up to 2.7.7. Affected by this issue is the function handle_scp_info in the library lib/sbi/nnrf-handler.c of the component Shared NF-profile Parser. This manipulation causes out-of-bounds write. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. To fix this issue, it is recommended to deploy a patch.

AnalysisAI

Out-of-bounds write in Open5GS versions up to 2.7.7 allows a remote, low-privileged attacker to crash the NRF (Network Repository Function) component by sending a malformed SCP info payload, resulting in a denial-of-service condition. The vulnerability resides in the handle_scp_info function within the Shared NF-profile Parser (lib/sbi/nnrf-handler.c), a critical parsing path for 5G service-based interface communication. …

Vulnerability AssessmentAI

Exploitation The CVSS vector (PR:L) confirms that low-privilege authenticated access to the 5G Service-Based Interface is required - unauthenticated exploitation is not supported. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 4.3 (Medium) is consistent with a limited-impact DoS requiring authenticated network access (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with low-level authenticated access to the 5G core's Service-Based Interface - such as a rogue or compromised Network Function client - sends a crafted HTTP/2 NF-profile registration or update request containing a malformed SCP info structure to the Open5GS NRF. The handle_scp_info parser writes beyond its allocated buffer boundary (CWE-787), corrupting adjacent memory and triggering a crash of the NRF process. …
Remediation The primary remediation is to apply the vendor-released patch addressing the out-of-bounds write in handle_scp_info. … Detailed patch versions, workarounds, and compensating controls in full report.
