Buffer underflow in bc_shift_addsub

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations.

DirectoryIterator class silently truncates after a null byte

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

link() silently truncates after a null byte on Windows

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

In SecurityCenter versions prior to 5.7.0, a cross-site scripting (XSS) issue could allow an authenticated attacker to inject JavaScript code into an image filename parameter within the Reports feature area. Properly updated input validation techniques have been implemented to correct this issue.

In SecurityCenter versions prior to 5.7.0, a username enumeration issue could allow an unauthenticated attacker to automate the discovery of username aliases via brute force, ultimately facilitating unauthorized access. Server response output has been unified to correct this issue.

SecurityCenter versions 5.5.0, 5.5.1 and 5.5.2 contain a SQL Injection vulnerability that could be exploited by an authenticated user with sufficient privileges to run diagnostic scans. An attacker could exploit this vulnerability by entering a crafted SQL query into the password field of a diagnostic scan within SecurityCenter. Successful exploitation of this vulnerability could allow an attacker to gain unauthorized access.

[R1] Stand-alone Security Patches Available for Tenable Security Center versions 6.5.1, 6.6.0 and 6.7.2: SC-202602.1 + SC-202602.2

A Command Injection vulnerability exists where an authenticated, remote attacker could execute arbitrary code on the underlying server where Tenable Security Center is hosted.

Indirect Object Reference (IDOR) in Security Center

An Indirect Object Reference (IDOR) in Security Center allows an authenticated remote attacker to escalate privileges via the 'owner' parameter.

Improper Access Control

An improper access control vulnerability exists where an authenticated user could access areas outside of their authorized scope.

An Improper Certificate Validation vulnerability exists in Tenable Security Center where an authenticated, privileged attacker could intercept email messages sent from Security Center via a rogue SMTP server.

Improper Access Control

In Tenable Security Center versions prior to 6.7.0, an improper access control vulnerability exists where an authenticated user could access areas outside of their authorized scope.

Command Injection Vulnerability in Tenable Security Center

A command injection vulnerability exists where an authenticated, remote attacker with administrator privileges on the Security Center application could modify Logging parameters, which could lead to the execution of arbitrary code on the Security Center host.

Improper privilege management

An improper privilege management vulnerability exists in Tenable Security Center where an authenticated, remote attacker could view unauthorized objects and launch scans without having the required privileges

Stored Cross Site Scripting

A stored cross site scripting vulnerability exists in Tenable Security Center where an authenticated, remote attacker could inject HTML code into a web application scan result page.

HTML Injection Vulnerability

An HTML injection vulnerability exists where an authenticated, remote attacker with administrator privileges on the Security Center application could modify Repository parameters, which could lead to HTML redirection attacks.
