Description
This security bulletin contains information about 1 vulnerability.
1) Code Injection (CVE-ID: CVE-2011-4453)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The PageListSort function in scripts/pagelist.php in PmWiki 2.x before 2.2.35 allows remote attackers to execute arbitrary code via PHP sequences in a crafted order parameter in a pagelist directive, leading to unintended use of the PHP create_function function.
