Vulnerability Description
In CWP (aka Control Web Panel or CentOS Web Panel) before 0.9.8.1107, an unauthenticated attacker can use %00 bytes to cause /user/loader.php to register an arbitrary API key, as demonstrated by a /user/loader.php?api=1&scripts= .%00./.%00./api/account_new_create&acc=guadaapi URI. Any number of %00 instances can be used, e.g., .%00%00%00./.%00%00%00./api/account_new_create could also be used for the scripts parameter.

II. Public POCs for CVE-2021-45467
#POC DescriptionSource LinkShenlong Link
1In CWP (Control Web Panel, previously CentOS Web Panel) before version 0.9.8.1107, an unauthenticated attacker can abuse null byte (%00) injection with the "scripts" parameter in the /user/loader.php or /user/login.php endpoints to register arbitrary API keys or access sensitive files. This can be exploited by using multiple %00 sequences to traverse directories via crafted requests such as /user/loader.php?api=1&scripts=.%00./.%00./api/account_new_create&acc=guadaapi, or similar payloads with more %00 instances (e.g., .%00%00%00./.%00%00%00./api/account_new_create). Attackers may use this flaw for arbitrary file access, privilege escalation, or remote code execution. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-45467.yamlPOC Details
