Heap over-read in PHP EXIF extension
Noroxi assessment
Priority: Monitor (action score 38/100)
- 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: 7% (FIRST EPSS); higher than 94% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: apcu-panel (AlmaLinux:8) 5.1.12-2.module_el8.3.0+2010+7c76a223; libzip (AlmaLinux:8) 1.5.1-2.module_el8.3.0+2010+7c76a223, 1.5.1-2.module_el8.5.0+53+9945c2af, 1.5.1-2.module_el8.4.0+2228+7c76a223; libzip-devel (AlmaLinux:8) 1.5.1-2.module_el8.3.0+2010+7c76a223, 1.5.1-2.module_el8.5.0+53+9945c2af, 1.5.1-2.module_el8.4.0+2228+7c76a223.
- Severity is disputed: the assigning authority (CNA) scores it 4.8, NVD 9.1.
Low priority for now. Upgrade to apcu-panel (AlmaLinux:8) 5.1.12-2.module_el8.3.0+2010+7c76a223; libzip (AlmaLinux:8) 1.5.1-2.module_el8.3.0+2010+7c76a223, 1.5.1-2.module_el8.5.0+53+9945c2af, 1.5.1-2.module_el8.4.0+2228+7c76a223; libzip-devel (AlmaLinux:8) 1.5.1-2.module_el8.3.0+2010+7c76a223, 1.5.1-2.module_el8.5.0+53+9945c2af, 1.5.1-2.module_el8.4.0+2228+7c76a223 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
When processing certain files, PHP EXIF extension in versions 7.1.x below 7.1.29, 7.2.x below 7.2.18 and 7.3.x below 7.3.5 can be caused to read past allocated buffer in exif_process_IFD_TAG function. This may lead to information disclosure or crash.

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.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
No commit or PR link among the references.
Credits

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.
