CVE-2021-44002
Status: ModifiedHigh (7.8)—
A vulnerability has been identified in JT Open (All versions < V11.1.1.0), JT Utilities (All versions < V13.1.1.0), Solid Edge (All versions < V2023). The Jt1001.dll contains an out of bounds write past the end of an allocated structure while parsing specially crafted JT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15058, ZDI-CAN-19076, ZDI-CAN-19077)
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Base score: 7.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 1.56%
- Percentile among all scored CVEs: 74
- Score date: 10/6/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
