Detailsinfo

A vulnerability, which was classified as problematic, was found in Zenitel Connect up to 1.10.x. This affects an unknown code of the component WAMP-CRA authentication path. The manipulation with an unknown input leads to a excessive authentication vulnerability. CWE is classifying the issue as CWE-307. The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame. This is going to have an impact on confidentiality. The summary by CVE is:

Improper restriction of excessive authentication attempts in the WAMP-CRA (challenge-response) authentication path in Zenitel Connect before 1.11.0 allows remote attackers to guess user passwords via unlimited authentication attempts, because the path, in which the broker issues a challenge and the client returns an HMAC of it keyed with the user's secret, applies no account lockout or rate limiting. Affected releases enforce a password policy of at least 12 characters including upper-case, lower-case, numeric and special characters, so practical exploitation requires a reused or predictable password rather than exhaustive guessing. The WAMP-CRA authentication path is removed in 1.11.0.

The advisory is shared at zenitel.com. This vulnerability is uniquely identified as CVE-2026-105622 since 10/05/2026. The exploitability is told to be difficult.

MITRE ATT&CK project uses the attack technique T1110.001 for this issue.
