CVE-2024-3378
Published: 06 April 2024
Summary
CVE-2024-3378 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Iboss Secure Web Gateway. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique JavaScript (T1059.007); ranked in the top 9.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A cross-site scripting vulnerability exists in iboss Secure Web Gateway versions up to 10.1. The flaw resides in an unknown function of the /login component within the Login Portal, where unsanitized input to the redirectUrl parameter allows injection of arbitrary script. It is tracked as CWE-79 and carries a CVSS 4.3 rating reflecting network attack vector, low complexity, and no required privileges, but with user interaction needed for payload delivery.
An unauthenticated remote attacker can supply a crafted redirectUrl value to trigger reflected XSS when a victim interacts with the login page. Successful exploitation permits the attacker to execute script in the victim's browser context, enabling actions such as theft of session tokens or manipulation of page content, though the vulnerability does not directly impact confidentiality or availability.
The vendor states that upgrading to version 10.2.0.160 resolves the issue. Publicly available references, including a detailed disclosure on GitHub, confirm the existence of working proof-of-concept code, and the EPSS score remains low and unchanged at 0.0554 with no observed increase after publication.
