CVE-2007-2488
HighSummary
Sterownik kanału IAX2 (chan_iax2) w Asterisku przed wersją 20070504 nieprawidłowo kończy dane znakiem null, co pozwala zdalnym atakującym na wywołanie utraty przesyłanych danych oraz potencjalne uzyskanie wrażliwych informacji (zawartości pamięci) lub spowodowanie awarii aplikacji (denial of service), wysyłając ramkę, która nie zawiera bajta 0.
Risk Assessment
Organizacja może być narażona na utratę danych oraz wyciek wrażliwych informacji, co może prowadzić do poważnych konsekwencji prawnych i reputacyjnych. Dodatkowo, możliwość awarii aplikacji może zakłócić działanie usług.
Recommendation
Zaleca się aktualizację Asteriska do wersji 20070504 lub nowszej, aby usunąć tę podatność. Należy również monitorować ruch sieciowy w celu wykrywania potencjalnych prób ataków.

Jumis (formerly Tildes Jumis) creates a Microsoft SQL Server login named ##Tilde_JumisAdmin## whose password is derived deterministically from a single non-secret input — the SQL Server name (@@servername). The derivation algorithm is hard-coded in the client application and identical across every installation, and it contains a hard-coded secret key. Because the only input (the server name) is not secret, anyone able to reach a Jumis SQL Server can compute the password offline and authenticate.

Craft CMS 4.0.0 before 4.18.9 and 5.0.0 before 5.11.2 contains an unauthenticated SQL injection vulnerability in the element search endpoint because the attribute parameter is concatenated into the query unsanitized and emulated PDO prepares allow stacked statements. Remote attackers can read and write the database, setting the admin flag or overwriting password hashes in the users table to gain administrator access.
- CVE-2026-114630Critical
The ELEX WordPress HelpDesk & Customer Ticketing System plugin is vulnerable to arbitrary file deletion due to insufficient file path validation in the factory_reset function in all versions up to, and including, 3.3.8. Unauthenticated attackers can delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The vulnerability is exploited via a two-step chain: storing an arbitrary ticket_attachment_path value through the public AJAX endpoint, then triggering the factory_reset routine via a GET request.
- CVE-2026-107622Critical
The BuddyForms plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.10.5 via a form-type confusion attack through the bf_post_type parameter. Unauthenticated attackers can insert a rogue BuddyForms form configuration with an attacker-controlled new_user_role value into the live global form registry, then submit a registration through that form to create a new WordPress account with administrator-level privileges. Exploitation requires "Anyone can register" enabled and at least one public BuddyForms form attached to a page.

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 act on a role deletion request on every page load with no capability check and no nonce. The guard meant to protect roles with assigned users reads a different part of the request than the one selecting what is deleted, allowing unauthenticated attackers to remove any WordPress role including administrator, permanently stripping every user of their capabilities.

Original NVD description (English source)
The IAX2 channel driver (chan_iax2) in Asterisk before 20070504 does not properly null terminate data, which allows remote attackers to trigger loss of transmitted data, and possibly obtain sensitive information (memory contents) or cause a denial of service (application crash), by sending a frame that lacks a 0 byte.
