CVE-2021-29620 | XXE vulnerability on Launch import with externally-defined DTD file

Report portal is an open source reporting and analysis framework. Starting from version 3.1.0 of the service-api XML parsing was introduced. Unfortunately the XML parser was not configured properly to prevent XML external entity (XXE) attacks. This allows a user to import a specifically-crafted XML file which imports external Document Type Definition (DTD) file with external entities for extraction of secrets from Report Portal service-api module or server-side request forgery. This will be resolved in the 5.4.0 release.

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:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
