Lifecycle Timeline
2DescriptionCVE.org
FOSSBilling is a free, open-source billing and client management system. Versions 0.6.0 through 0.7.2 have a SQL injection vulnerability in the Massmailer module filter functionality. An authenticated administrator can supply crafted filter values when updating a mass email message, causing untrusted input to be interpolated directly into SQL in the recipient selection query. Version 0.8.0 patches the issue. Some workarounds are available. Restrict administrator access to trusted users only, disable the Massmailer module if it is not required, audit existing records in the mod_massmailer table for suspicious filter values, and/or review administrator activity related to Massmailer message updates.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid, authenticated FOSSBilling administrator account - the CVSS 4.0 vector specifies PR:H. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.9 reflects the significant confidentiality impact tempered by the requirement for high-privilege (PR:H) administrator-level access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with valid FOSSBilling administrator credentials navigates to the Massmailer module and submits a crafted filter value - for example, a SQL UNION or boolean-based payload - in the recipient filter field of a mass email update request. The unsanitized value is interpolated into the backend recipient selection SQL query, allowing the attacker to enumerate database tables and extract sensitive records such as client personal data, billing information, or stored credentials. … |
| Remediation | The primary remediation is upgrading to FOSSBilling version 0.8.0, which patches the SQL injection in the Massmailer module per the vendor advisory at https://github.com/FOSSBilling/FOSSBilling/security/advisories/GHSA-jf7m-j359-2899. … Detailed patch versions, workarounds, and compensating controls in full report. |
