CVE-2015-5287
The abrt-hook-ccpp help program in Automatic Bug Reporting Tool (ABRT) before 2.7.1 allows local users with certain permissions to gain privileges via a symlink attack on a file with a predictable name, as demonstrated by /var/tmp/abrt/abrt-hax-coredump or /var/spool/abrt/abrt-hax-coredump.
do firstApply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
Can a WAF block it? No. The attack needs local access to the machine, so a WAF is not on its path.
Also consider: patch
Based on the attack vector (local or physical access). We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.
