CVE-2020-1031
HighSummary
Występuje podatność na ujawnienie informacji w usłudze DHCP serwera Windows, która niewłaściwie ujawnia zawartość swojej pamięci. Atakujący bez uwierzytelnienia może wysłać specjalnie przygotowany pakiet do podatnego serwera DHCP, co pozwala na uzyskanie informacji mogących prowadzić do dalszego kompromitowania systemu użytkownika.
Risk Assessment
Organizacja narażona jest na ryzyko ujawnienia wrażliwych informacji, co może prowadzić do dalszych ataków na systemy użytkowników. Potencjalny atakujący może wykorzystać te informacje do przeprowadzenia bardziej zaawansowanych działań złośliwych.
Recommendation
Zaleca się zastosowanie aktualizacji zabezpieczeń, która poprawia sposób inicjalizacji pamięci przez serwery DHCP, aby zniwelować tę podatność.

PyJWT is a Python implementation of JSON Web Token standards. Prior to version 2.14.0, is_pem_format in jwt/utils.py does not recognize every PEM representation accepted by the cryptography loader. When an application mixes HMAC and asymmetric algorithms and supplies a mutated public-key PEM as raw key bytes, HMACAlgorithm.prepare_key treats the unrecognized asymmetric public key as an HMAC secret. An attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6. The books() function in site/booklibrary.php reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect.
- CVE-2026-101108Critical
Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Vehicle Manager (Free) < 6.5.8. The site/vehiclemanager.php file reads the order_field and order_direction sort parameters at three separate anonymous-reachable frontend entry points (category listing, search, and the all-vehicles listing) through a sanitizing function that applies real escaping, but the value is then placed into an unquoted ORDER BY clause, where escaping has no protective effect.
- CVE-2026-100752Critical
Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Real Estate Manager (Free) < 6.7.9. The site/realestatemanager.php file builds the ORDER BY clause of three separate frontend property-listing queries (category browsing, search results, and the full property listing) from a request-controlled order_field parameter, concatenated directly into an unquoted SQL clause with no allow-list of real column names and no cast.
- CVE-2026-49994Critical
Bluehood monitors local bluetooth activity. Prior to version 0.7.1, when auth_enabled is set in Bluehood, only the HTML page handlers enforced session validation. The /api/* handlers (settings, devices, groups, per-device endpoints including /api/device/{mac}/notes) called no auth check at all. A network attacker reachable on the dashboard port could read Bluetooth tracking data and modify application state — including the heartbeat URL, prune retention, device groups, and per-device notes — without a session cookie. This issue has been patched in version 0.7.1.

An OS command injection vulnerability in the WatchGuard AP internal API service allows an attacker with network access to the AP to execute arbitrary shell commands on the underlying operating system.
Original NVD description (English source)
<p>An information disclosure vulnerability exists in the way that the Windows Server DHCP service improperly discloses the contents of its memory.</p> <p>To exploit the vulnerability, an unauthenticated attacker could send a specially crafted packet to an affected DHCP server. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.</p> <p>The security update addresses the vulnerability by correcting how DHCP servers initializes memory.</p>
