Juzaweb CMS before v3.4 allows remote authenticated attackers to execute arbitrary code via a crafted file uploaded through the custom plugin functionality.
Vulnerability
Overview CVE-2023-46468 is an arbitrary code execution vulnerability in juzaweb CMS versions 3.4 and earlier. The root cause lies in insufficient validation of files uploaded through the custom plugin feature, allowing an attacker to upload a malicious file that can be executed on the server [2].
Exploitation
Scenario An attacker must have at least plugin upload privileges (typically an admin-level role) to exploit this flaw. By crafting a PHP file (or other executable content) and uploading it as a plugin, the attacker can trigger execution via direct access or through the CMS's plugin loading mechanism [2][3]. The attack is remote and requires no special network position other than access to the administration panel.
Impact
Successful exploitation results in arbitrary code execution under the web server user context. This can lead to full compromise of the CMS instance, including data theft, privilege escalation, or further lateral movement within the hosting environment [2].
Mitigation
Status As of the CVE publication date (October 2023), no official patch had been confirmed for versions 3.4 and earlier. Users are advised to upgrade to a patched release if available, restrict plugin upload permissions, and implement file content validation. The vulnerability is not currently listed in the CISA KEV catalog [2].

Vulnerability mechanics
Root cause
"Improper neutralization of special elements in uploaded plugin files allows injection into a downstream component, enabling arbitrary code execution."
Attack vector
A remote attacker can upload a crafted file to the custom plugin functionality of juzawebCMS [ref_id=1]. Because the application does not properly neutralize special elements in the uploaded file, the file is interpreted or executed by a downstream component, leading to arbitrary code execution [CWE-74]. The attacker needs only network access to the CMS admin interface that exposes the plugin upload feature; no additional authentication requirements are documented in the advisory.
Affected code
The advisory does not specify the exact files or functions at fault. The vulnerability is described as affecting the "custom plugin function" in juzawebCMS v3.4 and earlier [ref_id=1]. No patch or code-level details are provided in the available references.
What the fix does
No patch or fix is published in the available references. The advisory links to a third-party exploit write-up but does not include a vendor-supplied remediation [ref_id=1]. To close the vulnerability, the application should validate and sanitize uploaded plugin files, rejecting any that contain executable code or special elements that could be passed to a downstream interpreter.
Preconditions
- networkAttacker must have network access to the juzawebCMS instance
- configThe CMS must expose the custom plugin upload functionality
- inputAttacker must be able to upload a crafted file (no authentication requirement specified)
