Threadlinqs Intelligence links 1 tracked threat campaign to CVE-2023-34362, most recently “Cl0p Ransomware MFT Attack Pattern: Multi-Year Zero-Day Campaigns Against File Transfer and Enterprise Software (2020-2025)”. **Last updated:** 2025-10-21 ## What is CVE-2023-34362? In Progress MOVEit Transfer before 2021.0.6 (13.0.6), 2021.1.4 (13.1.4), 2022.0.4 (14.0.4), 2022.1.5 (14.1.5), and 2023.0.1 (15.0.1), a SQL injection vulnerability has been found in the MOVEit Transfer web application that could allow an unauthenticated attacker to gain access to MOVEit Transfer's database. Depending on the database engine being used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker may be able to infer information about the structure and contents of the database, and execute SQL statements that alter or delete database elements. NOTE: this is exploited in the wild in May and June 2023; exploitation of unpatched systems can occur via HTTP or HTTPS. All versions (e.g., 2020.0 and 2019x) before the five explicitly mentioned versions are affected, including older unsupported versions. The record classifies CVE-2023-34362 under weakness class [CWE-89](https://intel.threadlinqs.com/cwe/CWE-89). Its CVSS v3 base vector states that the flaw is reachable remotely over the network, needs no prior authentication, needs no user interaction, and has high impact on confidentiality, integrity, availability. The identifier was first published 1226 days ago. ## Severity and exploitation probability - **CVSS v3.1 base score:** 9.8 — CRITICAL (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`) - **EPSS (FIRST):** 99.9% probability of exploitation in the next 30 days, higher than 99.9% of all scored CVEs - **CISA KEV:** Listed since 2023-06-02, federal remediation deadline 2023-06-23 — used in known ransomware campaigns - **Threadlinqs priority:** 10/10 — CISA lists it as used in ransomware, which Threadlinqs scores at the maximum - **Published:** 2023-06-02, last modified 2025-10-21 ## Is CVE-2023-34362 being exploited?
