Vulnerability description
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.
