CVE-2021-44153

Exp

An issue was discovered in Reprise RLM 14.2. When editing the license file, it is possible for an admin user to enable an option to run arbitrary executables, as demonstrated by an ISV demo "C:\Windows\System32\calc.exe" entry. An attacker can exploit this to run a malicious binary on startup, or when triggering the Reread/Restart Servers function on the webserver. (Exploitation does not require CVE-2018-15573, because the license file is meant to be changed in the application.)

Base score Version Severity Vector Exploitability Impact Score source
7.2 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H 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:H)
They need powerful rights—admin, root, or similar—before this pays off.
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:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
