SOGo before 5.12.13 Unauthenticated Password Recovery Brute Force

SOGo before 5.12.13 contains an improper restriction of excessive authentication attempts vulnerability that allows unauthenticated attackers to reset account passwords by repeatedly guessing secret-question answers via the passwordRecoveryCheck endpoint without lockout or rate limiting. Attackers can submit unlimited candidate answers to obtain a valid recovery JWT, then use it to change the account password without the old credential and log in via the connect endpoint, achieving full account takeover on accounts without TOTP enabled.

SOGo before 5.12.13 SSRF via Web Calendar Subscriptions

SOGo before 5.12.13 contains a server-side request forgery vulnerability that allows authenticated users to make the server connect to arbitrary internal host:port destinations by supplying a user-controlled URL to the Calendar/addWebCalendar endpoint. Attackers can trigger a reload of the subscribed web calendar via the reload endpoint and distinguish response outcomes such as connection failures, timeouts, authentication prompts, or invalid content to probe the internal network from the server's position.

SOGo before 5.12.13 S/MIME Certificate Spoofing via UIxMailView

SOGo before 5.12.13 contains an improper cryptographic signature verification vulnerability that allows remote attackers to replace a victim's contact S/MIME certificate by sending a spoofed multipart/signed message with a mismatched signature and an impersonated From address. Attackers can deliver a crafted CMS signedData object containing their own self-signed certificate, which SOGo's UIxMailView stores on the contact card without validating signature authenticity or certificate identity, enabling subsequent encrypted communications to be decrypted with the attacker's private key.

SOGo before 5.12.13 Missing Rate Limiting on TOTP Verification

SOGo before 5.12.13 contains a missing rate limiting vulnerability in its web login TOTP verification that allows attackers who already possess a victim's password to brute-force the second-factor code without triggering any lockout. Attackers can send repeated POST requests to /SOGo/connect with wrong verification codes at high speed since failed TOTP attempts never increment the failed-login counter and SOGoMaximumFailedLoginCount does not apply, enabling indefinite guessing across 30-second code windows to bypass two-factor authentication.

SOGo before 5.12.13 Sieve Script Injection via Notification Address

SOGo before 5.12.13 contains a Sieve script injection vulnerability that allows authenticated users to inject arbitrary Sieve directives by inserting unescaped notification address values into a generated Sieve script. Attackers can embed Sieve redirect or discard statements within the notificationAddress preference to bypass the administrator-configured forwarding-domain constraint and redirect or discard incoming mail.

SOGo before 5.12.13 Denial of Service via Auxiliary IMAP Account Greeting Wait

SOGo before 5.12.13 contains a denial of service vulnerability that allows authenticated attackers to exhaust all worker processes by configuring an auxiliary IMAP mail account pointing to a controlled host that accepts a TCP connection but never sends an IMAP greeting response. Attackers can issue concurrent GET requests to the mail view of this account to hold workers indefinitely without an effective timeout, occupying every SOGo worker and denying service to all users for approximately five minutes until the watchdog kills and respawns the stuck workers.

SOGo before 5.12.11 Password Reset Token Interception via Origin Header

SOGo before 5.12.11 constructs password-reset links using the client-supplied Origin header as the authority, allowing unauthenticated attackers to redirect recovery tokens to attacker-controlled domains. Attackers can submit password recovery requests with a malicious Origin header to have valid password-reset tokens mailed to victim recovery addresses within links pointing to attacker infrastructure, enabling account takeover.

Authenticated SQL Injection in SOGo Password‑Change API

A SQL injection vulnerability in SOGo before 5.12.7 allows authenticated users to execute arbitrary SQL statements via the newPassword parameter in the password change functionality.

Authenticated SQL Injection in SOGo Enabling Arbitrary Database Access

A SQL injection vulnerability in SOGo before 5.12.7 allows authenticated users to execute arbitrary SQL statements via the search parameter of the allContactSearch endpoint.

SOGo < 5.12.8 SQL Injection via addUserInAcls endpoint

SOGo versions 5.12.7 and prior contains a SQL injection vulnerability in the Access Control List management functionality that allows authenticated users to extract arbitrary data from the database by injecting SQL subqueries through the uid parameter of the addUserInAcls endpoint. Attackers can inject malicious SQL code to write extracted data into the sogo_acl table and retrieve it through the /acls API, establishing an out-of-band data exfiltration channel.

A cross-site scripting (XSS) vulnerability in Alinto SOGo, version 5.12.7

A cross-site scripting (XSS) vulnerability exists in Alinto SOGo, version 5.12.7. A maliciously crafted ICS calendar invitation files allows arbitrary JavaScript execution within the authenticated SOGo webmail session. The issue occurs because SVG content embedded in the description field of an ICS file, with an onrepeat event handler, is insufficiently sanitized before being rendered in the webmail interface. A remote attacker can execute JavaScript in the victim's browser when the malicious calendar invite is viewed. Successful exploitation may allow mailbox access, email and contact theft, session hijacking, and other actions allowed by an authenticated user.

SOGo Webmail Server SQL Injection via PostgreSQL

SOGo before 5.12.7, when PostgreSQL is used, allows SQL injection.

SQL Injection via Password Change Endpoint in Alinto SOGo <5.12.7 Using Cleartext Passwords

SOGo before 5.12.7, when PostgreSQL or MariaDB is used, and cleartext passwords are stored, allows SQL injection. This is related to c_password = '%@' in changePasswordForLogin.

Alinto SOGo cross site scripting

A vulnerability was identified in Alinto SOGo 5.12.3/5.12.4. This impacts an unknown function. The manipulation of the argument hint leads to cross site scripting. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

In Alinto SOPE SOGo 2.0.2 through 5.12.2, sope-core/NGExtensions/NGHashMap.m allows a NULL pointer dereference and SOGo crash via a request in which a parameter in the query string is a duplicate of a parameter in the POST body.

Unsanitized Category Names Allow Cross‑Site Scripting in SOGo

SOGo before 5.12.5 is prone to a XSS vulnerability with events, tasks, and contacts categories.

Insufficient OTP Renewal and Length in SOGo Leading to Potential Credential Compromise

SOGo before 5.12.5 does not renew the OTP if a user disables/enables it, and has a too short length (only 12 digits instead of the 20 recommended).

alinto SOGo 5.12.3 is vulnerable to Cross Site Scripting (XSS) via the "userName" parameter.

Alinto Sogo 5.12.3 is vulnerable to Cross Site Scripting (XSS) via the theme parameter.

Alinto SOGo before 5.9.1 is vulnerable to HTML Injection.
