CVE-2021-44000

A vulnerability has been identified in JT2Go (All versions < V13.2.0.7), Solid Edge SE2021 (All versions < SE2021MP9), Solid Edge SE2022 (All versions < SE2022MP1), Teamcenter Visualization V13.1 (All versions < V13.1.0.9), Teamcenter Visualization V13.2 (All versions < V13.2.0.7), Teamcenter Visualization V13.3 (All versions < V13.3.0.1). The plmxmlAdapterSE70.dll contains an out of bounds write past the fixed-length heap-based buffer while parsing specially crafted PAR files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15053)

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
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: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.

Access vector (AV:N)
Can be exploited remotely over network reachability.
Access complexity (AC:M)
Exploitation needs some favorable conditions, but not exceptional ones.
Authentication (AU:N)
No authentication is required.
Confidentiality impact (C:P)
Partial confidentiality impact.
Integrity impact (I:P)
Partial integrity impact.
Availability impact (A:P)
Partial availability impact.
