HighCVSS 7.5
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.27%

19th percentile - higher than 19% of all known CVEs

Summary

In osmo-bsc from 1.0.1 through 1.14.1, a heap-based buffer overflow issue was found in the ipaccess_proxy_read_msg() function via IPA frame lengths. This can lead to memory corruption.

Risk Assessment

A heap-based buffer overflow may allow an attacker to execute arbitrary code or cause a service crash. The risk is high if the service is exposed to untrusted networks.

Recommendation

Update osmo-bsc to a version later than 1.14.1 if available. Otherwise, consider network segmentation and restricting access to IPA interfaces.
