Public exploitAvailablePublished on Exploit-DB
The resource system in PHP 5.0.0 through 5.2.1 allows context-dependent attackers to execute arbitrary code by interrupting the hash_update_file function via a userspace (1) error or (2) stream handler, which can then be used to destroy and modify internal resources. NOTE: it was later reported that PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 are also affected.
CVSS
- Base score
- 9.3
- Version

- Vector
- AV:N/AC:M/Au:N/C:C/I:C/A:C
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days
- 8.03 %
- Percentile among all scored CVEs

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
