Red TIM Research (RTR) founds 2 bugs affecting F5 Traffix SDC

Experts at TIM research laboratory, Red Team Research (RTR), have disclosed a couple of bugs affecting F5 Traffix SDC.

Among these 45 bugs fixed by the well-known manufacturer of computer security systems, 2 were detected by TIM research laboratory, Red Team Research (RTR), as part of the bug hunting activities, on the F5® Traffix® Signaling Delivery Controller (SDC) solution.

F5 Traffix Signaling Delivery Controller

F5® Traffix® Signaling Delivery Controller (SDC) solution helps operators to scale and manage services and applications in 4G/LTE networks.

It also allows the routing and exchange of data between different protocols, such as Diameter, SS7, HTTP etc. It uses an advanced transformation and flow management engine while satisfying the increasing demand for services and broadband subscribers.

SDC solution can be configured and monitored through a web user interface that has been detected as vulnerable to 2 security bugs found by Red TIM Research recently.

According to the institutional website https:///www.gruppotim.it/redteam, once these vulnerabilities were identified, researchers Valerio Alessandroni and Matteo Brutti immediately started the process of Coordinated Vulnerability Disclosure (CVD) with Massimiliano Brolli, leading the project, by publishing only after the availability of the fixes made by the Vendor.

Detected 0day Overview

Below are the bugs detected on F5 SDC that have been published on the institutional website, available at this address: https://www.gruppotim.it/redteam

CVE-2022-27880

• Vulnerability Description: Stored Cross-Site Scripting – CWE-79
• Software Version: 5.1.0, 5.2.0
• NIST: https://nvd.nist.gov/vuln/detail/CVE-2022-27880
• CVSv3: TBD
• Severity: TBD
• The Web application of F5 SDC doesn’t check properly the parameters sent as input in HTTP requests, before saving them in the server. In addition, the JavaScript malicious content is then reflected back to the end user and executed by the web browser.

CVE-2022-27662

• Vulnerability Description: Stored Client-Side Template Injection-CWE-1336
• Software Version: 5.1.0, 5.2.0
• NIST: https://nvd.nist.gov/vuln/detail/CVE-2022-27662
• CVSv3: TBD
• Severity: TBD
• In Traffix Signal Delivery Controller 5.1.0 and 5.2.0, stored client-side template injection (CSTI) was possible, which could lead to code execution.

We are talking about one of the few Italian centers of industrial research about security bugs, where since few years are performed “bug hunting” activities that aim to search for undocumented vulnerabilities, leading to a subsequent issuance of a Common Vulnerabilities and Exposures (CVE) on the National Vulnerability Database of the United States of America, once the Coordinated Vulnerability Disclosure (CVD) with the Vendor is over.

In two years of activity, the team has detected many 0-days on very popular products of big vendors, such as Oracle, IBM, Ericsson, Nokia, Computer Associates, Siemens, QNAP, Johnson & Control, Schneider Electric, as well as other vendors on different types of software architectures.

In two years, more than 70 CVEs have been published, 4 of them with a Critical severity (9.8 of CVSSv3 scores), 23 of them with a High severity and 36 of them with a Medium severity.

Speaking about a vulnerability detected on Johnson & Control’s Metasys Reporting Engine (MRE) Web Services Product, Cybersecurity and Infrastructure Security Agency (CISA) of the United States of America issued a specific Security Bulletin reporting as Background the following sectors: “CRITICAL INFRASTRUCTURE SECTORS, COUNTRIES/ AREAS USED and COMPANY HEADQUARTERS”.

It is an all-Italian reality that issues a CVE every 6 working days, internationally contributing to the research for undocumented vulnerabilities, contributing to the security of the products used by many organizations and several individuals.
