Tim’s RED Team Research reports 3 new CVEs, two of which in 4G/5G

Telecom Italia Red Team Research (RTR) laboratory led by Massimiliano Brolli reported three new flaws in Oracle GlassFish and Nokia NetAct.

Telecom Italia Red Team Research (RTR) laboratory led by Massimiliano Brolli, reported three new vulnerabilities affecting Oracle GlassFish and Nokia NetAct, as reported on the online project’s page.

Two vulnerabilities affect Nokia NetAct, a mobile network management system, offering a centralized view of multi-technology networks, as 5G, 4G, 3G and 2G. The system offers built-in management of all the best daily operations without interruptions, including configuration management, monitoring, and software management. NetAct supports network elements in both radio mobile and core network, Wi-Fi, IoT, public security and telco cloud.

The last vulnerability has been found in GlassFish, an Oracle’s product that offers full support to Java EE 8 specifications (it is the reference implementation) with last API’s versions for technologies as Java Servlet 4, JavaServer Pages (JSP 2.3), Enterprise JavaBeans (EJB 3.2), Java Persistence API (JPA 2.1).

The vulnerabilities have been discovered by Red Team Research’s researchers and promptly reported to the respective vendors where the relevant CVEs were subsequently issued, then, published in the National Vulnerability Database of the United States of America and finally, listed by NIST.

• CVE-2021-26597 – NOKIA NetAct
  • Vulnerability Description: Unrestricted Upload of File with Dangerous Type – CWE-434
  • Software Version: NOKIA NetAct 18A
  • NIST: https://nvd.nist.gov/vuln/detail/CVE-2021-26597
  • Credits: Raffaella Robles, Andrea Carlo Maria Dattola, Massimiliano Brolli
  • An issue was discovered in Nokia NetAct 18A. A remote user, authenticated to the NOKIA NetAct Web Page, can visit the Site Configuration Tool web site section and arbitrarily upload potentially dangerous files without restrictions via the /netact/sct dir parameter in conjunction with the operation=upload value.

• CVE-2021-26596 – NOKIA NetAct
  • Vulnerability Description: Improper Neutralization of Input During Web Page Generation (Stored Cross-Site Scripting) – CWE-79
  • Software Version: NOKIA NetAct 18A
  • NIST: https://nvd.nist.gov/vuln/detail/CVE-2021-26596
  • Credits: Raffaella Robles, Andrea Carlo Maria Dattola, Massimiliano Brolli
  • An issue was discovered in Nokia NetAct 18A. A malicious user can change a filename of an uploaded file to include JavaScript code, which is then stored and executed by a victim’s web browser. The most common mechanism for delivering malicious content is to include it as a parameter in a URL that is posted publicly or e-mailed directly to victims. Here, the /netact/sct filename parameter is used.

• CVE-2021-3314 – Oracle GlassFish Server
  • Vulnerability Description: Improper Neutralization of Input During Web Page Generation (Cross-Site Scripting) – CWE-79
  • Software Version: <= 3.1.2.18
  • NIST:  https://nvd.nist.gov/vuln/detail/CVE-2021-3314
  • Credits: Francesco Giordano, Massimiliano Brolli

** UNSUPPORTED WHEN ASSIGNED ** Oracle GlassFish Server 3.1.2.18 and below allows /common/logViewer/logViewer.jsf XSS. A malicious user can cause an administrator user to supply dangerous content to the vulnerable page, which is then reflected back to the user and executed by the web browser. The most common mechanism for delivering malicious content is to include it as a parameter in a URL that is publicly posted or sent via email to victims. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

TIM zeroday research laboratory is working for a year and a half (according to the first CVE issued) and 52 undocumented vulnerabilities have already been identified, on various products including NOKIA, Oracle, Siemens, IBM, Selesta, Johnson & Controls, Schneider Electric and others.

TIM is one of the very few Italian industrial companies to conduct research into undocumented vulnerabilities and this project is unique in its kind.
