Bitrix24

Bitrix24 is a narrowly scoped collaboration and business-management platform whose vulnerability profile punches above its modest product footprint, with disclosures affecting core components including the main Bitrix24 offering, Site Manager, and the underlying framework. Vulnerabilities affecting this vendor skew toward critical severity and frequently acquire public exploit code, reflecting the platform's web-facing nature and the appeal of its widely deployed enterprise instances to attackers seeking compromise and lateral movement. The exposure recurs across input-handling, authentication, and file-handling boundaries through weakness classes including cross-site scripting, insufficiently protected credentials, unrestricted file uploads, cleartext sensitive-data storage, and untrusted deserialization—patterns characteristic of web-application stacks where user input flows directly into templating and serialization logic. Defenders should treat Bitrix24 advisories as high-priority, particularly for internet-exposed instances and administrative interfaces; current severity, exploitation activity, and exposure counts are shown alongside this summary.
