A code injection vulnerability has been identified in 08CMS Novel System versions 3.0 to 3.4. This flaw resides within the component's Template Handler, specifically the file admina/mtpls.inc.php, allowing attackers to inject and potentially execute malicious code. The vulnerability is remotely exploitable and has been publicly disclosed, increasing the risk of immediate exploitation. A patch is available in version 3.4.1.
Successful exploitation of CVE-2025-15250 allows an attacker to inject and execute arbitrary code on the affected server. This could lead to complete system compromise, including data exfiltration, modification, or deletion. The attacker could potentially gain control of the entire 08CMS Novel System installation, impacting any sensitive data stored within the system, such as user credentials, novel content, or administrative settings. Given the remote accessibility of the vulnerability, the blast radius extends to anyone with network access to the server.
This vulnerability has been publicly disclosed, increasing the likelihood of exploitation. While no specific active campaigns have been reported, the availability of public information makes it a prime target for opportunistic attackers. The vulnerability is not currently listed on CISA KEV, but its public disclosure warrants close monitoring. The ease of exploitation suggests a medium probability of exploitation.
Organizations utilizing 08CMS Novel System for content management, particularly those hosting the system on shared hosting environments or with limited security controls, are at increased risk. Legacy installations with outdated configurations and weak access controls are also particularly vulnerable.
