DescriptionCVE.org

A CMS contains a SQL injection vulnerability in admin/db_data.php at line 509 that allows authenticated administrators to inject arbitrary SQL into a SHOW COLUMNS FROM statement by supplying unsanitized input through the table_name GET or POST parameter. Attackers can perform table traversal, time-based blind, boolean-based blind, and error-based injection techniques to enumerate full database schema, access system tables such as information_schema, and chain the disclosure with secondary injection points to extract credential data.

AnalysisAI

SQL injection in Saurus CMS Community Edition's admin panel grants authenticated administrators the ability to fully enumerate and extract data from the underlying database. The flaw resides in admin/db_data.php at line 509, where the table_name GET or POST parameter is passed unsanitized into a SHOW COLUMNS FROM SQL statement, enabling time-based blind, boolean-based blind, and error-based injection techniques that expose the full schema and can be chained to extract credential data. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with administrator-level privileges within Saurus CMS, as confirmed by the CVSS 4.0 PR:H metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 8.6 with vector AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H reflects a technically straightforward exploitation path once administrator credentials are obtained, with high impact across confidentiality, integrity, and availability of the vulnerable system's database. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained Saurus CMS administrator credentials - through phishing, credential stuffing, or a compromised account - navigates to admin/db_data.php and submits a crafted table_name parameter using the publicly available proof-of-concept as a template. Error-based or time-based blind injection techniques are used to enumerate the full database schema via information_schema, and the attacker pivots to extract stored user credentials or session tokens. …
Remediation No vendor-released patch has been identified at time of analysis - the CPE wildcard version field confirms no fixed release is documented. … Detailed patch versions, workarounds, and compensating controls in full report.
