CVE-2025-53645
HighSummary
Zimbra Collaboration (ZCS) przed wersją 9.0.0 Patch 46, 10.0.x przed 10.0.15 oraz 10.1.x przed 10.1.9 jest podatna na atak typu denial of service z powodu niewłaściwego przetwarzania nadmiarowych segmentów ścieżki oddzielonych przecinkami w Konsoli Administracyjnej. Nieautoryzowany zdalny atakujący może wysłać specjalnie przygotowane żądania GET, które powodują nadmiarowe przetwarzanie i zwiększone odpowiedzi.
Risk Assessment
To prowadzi do niekontrolowanego zużycia zasobów, co skutkuje odmową usługi. Organizacje mogą doświadczyć przerw w dostępności usług, co wpływa na ich operacje.
Recommendation
Zaleca się aktualizację Zimbra Collaboration do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto monitorować ruch do Konsoli Administracyjnej w celu wykrywania potencjalnych ataków.

X-SpringBoot through 6.0 ships with a hardcoded static master login verification code 172839 enabled by default in the database seed. Unauthenticated attackers can authenticate as any user by submitting the public master code to the emailOrMobileLogin endpoint with a known email or mobile number.

X-SpringBoot through 6.0 returns login verification codes in HTTP responses from unauthenticated endpoints GET /sys/mobile/code and GET /sys/email/code without sending them to account owners. Attackers can request codes using known mobile numbers or email addresses, read them from responses, and authenticate as victims via POST /sys/emailOrMobileLogin/login to hijack accounts.
- CVE-2026-84458Critical
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when the "Automatic account link on initial logon" setting is enabled, Zammad binds an incoming third-party (SSO) identity to an existing local account by matching the email address the identity provider reports, without verifying that the provider actually confirmed ownership of that email. An attacker who controls any identity at a configured provider, including, by default, any Azure AD tenant via Zammad's multi-tenant Microsoft 365 /common app registration, can set that identity's email to a victim's address, authenticate, and be logged in as the victim. This bypasses the victim's local password entirely and affects any existing account, including agents and administrators. Zammad will honor the xms_edov ID token claim when email verification is required in the Microsoft 365 setting, treating a missing claim as unverified. This issue is fixed in version 7.1.2.

GLPI is a free asset and IT management software package. From 11.0.0 until 11.0.8, a form administrator can use Form import with a crafted illustration or scene identifier that traverses outside the intended custom-asset directory.

Before versions 1.7.4 and 2.0.0-beta.4, the Discord OAuth provider in FriendsOfFlarum does not check the 'verified' field for an OAuth email before passing it to Flarum core as trusted. This allows an unauthenticated attacker who knows a victim's email address to configure a Discord account with that unverified address and sign in as the victim without a password.

Original NVD description (English source)
Zimbra Collaboration (ZCS) before 9.0.0 Patch 46, 10.0.x before 10.0.15, and 10.1.x before 10.1.9 is vulnerable to a denial of service condition due to improper handling of excessive, comma-separated path segments in the Admin Console. An unauthenticated remote attacker can send specially crafted GET requests that trigger redundant processing and inflated responses. This leads to uncontrolled resource consumption, resulting in denial of service.
