CVE-2024-47249: Apache NimBLE: Lack of input sanitization leading to out-of-bound reads in multiple advertisement handler

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.62% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Apache Software Foundation Apache NimBLE 1.8.0.

Low priority for now. Upgrade to Apache Software Foundation Apache NimBLE 1.8.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper Validation of Array Index vulnerability in Apache NimBLE. Lack of input validation for HCI events from controller could result in out-of-bound memory corruption and crash. This issue requires broken or bogus Bluetooth controller and thus severity is considered low. This issue affects Apache NimBLE: through 1.7.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
