CVE-2017-18362
SQLi in Connectwise Manageditsync ≤ 2017
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2017-18362 is a critical-severity SQL Injection (CWE-89) vulnerability in Connectwise Manageditsync. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 0.3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2017-18362 affects the ConnectWise ManagedITSync integration through 2017 for Kaseya VSA. The flaw stems from exposure of the ManagedIT.asmx page in the Kaseya VSA web interface, which permits unauthenticated remote execution of arbitrary SQL queries with both read and write access to the underlying database. The issue is classified under CWE-89 and carries a CVSS 3.1 base score of 9.8.
An attacker who can reach the affected page can issue direct SQL commands against the VSA database without supplying credentials. Successful exploitation grants full control over managed endpoint data and configuration, enabling actions such as deploying payloads across all systems monitored by the VSA server. In February 2019, threat actors actively used the vulnerability in the wild to download and execute ransomware on those endpoints.
Public references, including Kaseya advisory pages and related repositories, document the exposure and exploitation activity but do not detail specific patch versions or configuration changes within the supplied information.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.
Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only improves knowledge flow, awareness of threats/patches and access to specialist advice; it does not stop SQL injection from being exploitable in code that still contains the flaw.
