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 Exploit Public-Facing Application (T1190); 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.

PR.PS-06 mostly match
prevents

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.

PR.AT-02 partial match
prevents

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.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
