Overview<\/strong><\/p>\n

CVE-2025-45890 represents a severe directory traversal vulnerability in Novel Plus versions preceding v.5.1.0. A remote attacker can exploit this weakness to execute arbitrary code, potentially compromising the system and leaking sensitive data. This vulnerability matters significantly due to its high severity<\/a> score and the potential for widespread data loss or unauthorized system access. As such, it is crucial for anyone using Novel Plus to understand this vulnerability and take immediate steps to mitigate<\/a> its effects.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-45890
\nSeverity: Critical (CVSS Score: 9.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Novel Plus | Before v.5.1.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit leverages a directory traversal vulnerability<\/a> in Novel Plus. Specifically, the vulnerability lies in the improper<\/a> handling of the ‘filePath’ parameter. By sending specially crafted requests, an attacker can manipulate the ‘filePath’ parameter to traverse directories and execute arbitrary code<\/a> remotely. This exploitation can lead to unauthorized<\/a> system access and potential data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

A conceptual example of how this vulnerability might be exploited might look like this:<\/p>\n

GET \/download?filePath=..\/..\/..\/..\/etc\/passwd HTTP\/1.1\nHost: target.example.com<\/code><\/pre>\n
In this example, the attacker uses the ‘filePath’ parameter to traverse to the ‘etc\/passwd’ directory, a common target as it stores user account<\/a> details. A successful exploit could allow the attacker to gain unauthorized access<\/a> to sensitive data.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability<\/a>, users are advised to apply the vendor patch immediately. If unable to apply the patch right away, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can help identify and block malicious requests that attempt to exploit this vulnerability<\/a>. However, they should not replace the long-term solution of patching the affected software.<\/p>\n","protected":false},"excerpt":{"rendered":"
