Secure Connect Gateway (SCG) Policy Manager: Improper Neutralization of Input During Web Page Generation

CVE-2024-24906 is a high-severity improper neutralization of input during web page generation vulnerability in Secure Connect Gateway (SCG) Policy Manager from Dell, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited from the same local network by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. The record lists version 5.22.00.16 as the first without the flaw, so updating Secure Connect Gateway (SCG) Policy Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.42% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Dell Secure Connect Gateway (SCG) Policy Manager, all versions, contain(s) a Stored Cross-Site Scripting Vulnerability in Policy page. An adjacent network high privileged attacker could potentially exploit this vulnerability, leading to the storage of malicious HTML or JavaScript codes in a trusted application data store. When a victim user accesses the data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application. Exploitation may lead to information disclosure, session theft, or client-side request forgery.

The underlying weakness: Improper Neutralization of Input During Web Page Generation

The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
  • Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
