Reduced browser protections via missing security headers
Published Jan 23, 2020 · Updated Aug 5, 2024
Missing HTTP security headers in ConnectWise Control 19.3.25270.7185 allows remote attackers to weaken browser-side protections. The application’s HTTP responses omit HSTS and CSP, so browsers receive no instruction to enforce HTTPS or restrict permitted content sources. Remote unauthenticated access is sufficient to observe the condition, but exploitation requires a separate browser or content attack; the omission alone does not directly disclose or modify data.
