A directory traversal flaw exists in Next4Biz Information Technologies Inc. CSM (Customer Service Management) that allows an attacker to reference files outside the intended directory. The vulnerability can be triggered by manipulating path inputs, potentially giving an attacker the ability to read sensitive files or local configuration data. No injection or code execution vector is explicitly disclosed, so the impact is confined to confidentiality and integrity of exposed files.

Next4Biz Information Technologies Inc. Customer Service Management from version 6.8.9 up to but not including 8.0.3 are impacted. All installations within this version range are vulnerable.

The CVSS score of 7.5 classifies the flaw as high severity. The EPSS score is 1.76%, indicating a non‑negligible likelihood of exploitation. The vulnerability is not listed in CISA KEV, indicating no known large‑scale exploitation. Based on the description, it is inferred that the vulnerability is exploitable over the network through the web interface of CSM, as path parameters are user‑controllable. Without a vendor response or official fix, the risk remains significant for exposed deployments.
