CVE-2023-25601 | Apache DolphinScheduler 3.0.0 to 3.1.1 python gateway has improper authentication

On version 3.0.0 through 3.1.1, Apache DolphinScheduler's python gateway suffered from improper authentication: an attacker could use a socket bytes attack without authentication. This issue has been fixed from version 3.1.2 onwards. For users who use version 3.0.0 to 3.1.1, you can turn off the python-gateway function by changing the value `python-gateway.enabled=false` in configuration file `application.yaml`. If you are using the python gateway, please upgrade to version 3.1.2 or above.

4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/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:L)
A normal user session is enough; they don’t have to be admin.
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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
