CVE-2010-1129

Status: ModifiedHigh (7.5)—
Severity7.5High · CVSS 2.0
Exploitation probability2.59 %higher than 85% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

The safe_mode implementation in PHP before 5.2.13 does not properly handle directory pathnames that lack a trailing / (slash) character, which allows context-dependent attackers to bypass intended access restrictions via vectors related to use of the tempnam function.
