CVE-2016-3406
HighSummary
Multiple cross-site request forgery (CSRF) vulnerabilities in Zimbra Collaboration before version 8.7.0 allow remote attackers to hijack the authentication of unspecified victims via vectors involving the Client uploader extension or extension REST handlers.
Risk Assessment
Attackers can exploit these vulnerabilities to hijack user sessions, potentially leading to unauthorized access to system data and functions.
Recommendation
It is recommended to update Zimbra Collaboration to version 8.7.0 or later to mitigate these vulnerabilities.

- CVE-2016-3402High
Unspecified vulnerability in Zimbra Collaboration before version 8.7.0 allows remote attackers to affect confidentiality via unknown vectors.
- CVE-2026-73570HighActively exploited
A remote code execution vulnerability exists in Zimbra Collaboration (ZCS) before 10.1.20 when the optional zimbra-snmp package is installed and SNMP notifications are enabled. Due to improper sanitization of untrusted input during SNMP notification processing, an unauthenticated attacker can send specially crafted SMTP requests that may result in execution of arbitrary operating system commands as the Zimbra user.
- CVE-2022-27924HighActively exploited
Zimbra Collaboration (ZCS) 8.8.15 and 9.0 allows an unauthenticated attacker to inject arbitrary memcache commands into a targeted instance. These memcache commands become unescaped, causing an overwrite of arbitrary cached entries.
- CVE-2016-3415Critical
Zimbra Collaboration before version 8.7.0 allows remote attackers to conduct deserialization attacks via unspecified vectors.
- CVE-2026-73576Medium
In Zimbra Collaboration (ZCS) before 10.1.17, there is a vulnerability involving weak cryptographic key generation in the OnlyOffice integration. The JWT secret (zimbraDocumentEditingJwtSecret) is generated using an insecure random number generator, resulting in insufficient entropy. An attacker who obtains a JWT signed with this secret may be able to recover it through offline brute-force, potentially enabling JWT forgery.
- CVE-2026-73575Low
In Zimbra Collaboration (ZCS) before 10.1.17, a Cross-Site Request Forgery (CSRF) vulnerability exists in the Exchange Web Services (EWS) endpoint of Zimbra Collaboration (ZCS) due to insufficient validation of request content types. An attacker can exploit this vulnerability by causing an authenticated user to submit a crafted request, potentially allowing unauthorized actions to be performed on behalf of the victim.
Original NVD description (English source)
Multiple cross-site request forgery (CSRF) vulnerabilities in Zimbra Collaboration before 8.7.0 allow remote attackers to hijack the authentication of unspecified victims via vectors involving (1) the Client uploader extension or (2) extension REST handlers, aka bugs 104294 and 104456.
