CVE-2024-6398

An information disclosure vulnerability in SWG in versions 12.x prior to 12.2.10 and 11.x prior to 11.2.24 allows information stored in a customizable block page to be disclosed to third-party websites due to Same Origin Policy Bypass of browsers in certain scenarios. The risk is low, because other recommended default security policies such as URL categorization and GTI are in place in most policies to block access to uncategorized/high risk websites. Any information disclosed depends on how the customers have customized the block pages.

Base score Version Severity Vector Exploitability Impact Score source
4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
