Remote Code Execution

A command injection vulnerability exists in Tenable Security Center. An authenticated administrator could modify application configuration values to achieve arbitrary command execution on the underlying operating system when specific backend operations are triggered.

Privilege Escalation

A privilege escalation vulnerability exists in Tenable Security Center that allows a user with "Security Manager" role and "manage user" permission on a single group to modify users belonging to other groups. This bypasses the intended access control restrictions and enables unauthorized cross-group user management.

SQL Injection

A SQL injection vulnerability exists in Security Center that could allow an authenticated administrator to execute arbitrary SQL queries, potentially resulting in unauthorized access to sensitive data, including credentials.

Improper Input Validation

An input validation vulnerability exists in Security Center's file upload handling, where insufficient sanitization of uploaded filenames could contribute to a downstream command injection issue.

Remote Code Execution

A remote code execution vulnerability exists in Tenable Security Center's report generation functionality. An authenticated, non-administrative user could exploit this issue by supplying specially crafted input that is later processed unsafely during server-side report rendering, resulting in arbitrary code execution with the privileges of the service account.

Local Privilege Escalation

A local privilege escalation vulnerability exists in Security Center. An attacker with write access to a specific configuration file could achieve arbitrary code execution with elevated privileges, without requiring further user or victim interaction.

Insuffucient Protections Lead to Brute Force

An issue was identified in which CSRF tokens were generated using a predictable method, potentially reducing their effectiveness as a security control. This has been addressed by improving the randomness and entropy of token generation.

Improper Access Control

An improper access control vulnerability exists where an authenticated non-administrative application user could potentially view settings outside of their assigned scope.

SQL Injection

A SQL injection vulnerability exists in Security Center that could allow an attacker to access unauthorized data from the application's database.

Command Injection

An authenticated command injection vulnerability exists in Security Center related to file upload processing. An attacker could exploit this issue by uploading a specially crafted file, potentially resulting in arbitrary command execution on the underlying operating system.

Command Injection

A command injection vulnerability exists in Security Center where a remote, unauthenticated attacker could exploit this issue to execute arbitrary commands on the underlying operating system with the privileges of the service account.

Blind SQL Injection

Unsanitized user-supplied input in report filtering parameters is concatenated directly into SQL queries without proper escaping or parameterized queries, enabling blind SQL injection and unauthorized database read access.

Command Injection

A filename supplied during file upload is not properly sanitized before being used in system command execution, allowing an attacker to inject shell metacharacters and achieve command injection via the audit file upload functionality.

Command Injection

Unvalidated input in asset filter parameters allows shell metacharacters to escape command argument handling, resulting in remote code execution as a low-privileged OS user via the Analysis REST endpoint.

SQL Injection in Tenable Security Center Ticketing API Exposes Sensitive Data

An authenticated non-admin user can exploit a SQL injection flaw in the ticketing REST API to access sensitive data stored in the appliance database.

Command Injection

The audit file upload handler does not sanitize filenames, allowing shell metacharacters to flow into system command execution. This input validation failure enables command injection when chained with a related vulnerability.

Cross-site scripting (XSS) vulnerability in devform.php in Tenable SecurityCenter 4.6 through 4.7 allows remote attackers to inject arbitrary web script or HTML via the message parameter.

Tenable Plugin Feed ID #202306261202 Fixes Privilege Escalation Vulnerability

Vulnerability in Tenable Tenable.Io, Tenable Nessus, Tenable Security Center.This issue affects Tenable.Io: before Plugin Feed ID #202306261202 ; Nessus: before Plugin Feed ID #202306261202 ; Security Center: before Plugin Feed ID #202306261202 . This vulnerability could allow a malicious actor with sufficient permissions on a scan target to place a binary in a specific filesystem location, and abuse the impacted plugin in order to escalate privileges.

Use-after-free in exif parsing under memory sanitizer

When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash.

mail() may release string with refcount==1 twice

In PHP versions 7.3.x below 7.3.13 and 7.4.0 on Windows, when supplying custom headers to mail() function, due to mistake introduced in commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, if the header is supplied in lowercase, this can result in double-freeing certain memory locations.
