CVE-2020-13799
MediumCVSS 6.8Summary
Firma Western Digital zidentyfikowała podatność bezpieczeństwa w protokole Replay Protected Memory Block (RPMB), który jest określony w wielu standardach interfejsów urządzeń pamięci masowej, w tym we wszystkich wersjach eMMC, UFS i NVMe. Istnieje kilka scenariuszy, w których stan RPMB może być zmieniony przez atakującego bez wiedzy zaufanego komponentu korzystającego z funkcji RPMB.
Risk Assessment
Podatność ta może prowadzić do naruszenia integralności zaufanego oprogramowania układowego, co stwarza ryzyko dla bezpieczeństwa systemów korzystających z urządzeń pamięci masowej. Atakujący mogą manipulować stanem RPMB, co może skutkować nieautoryzowanym dostępem do zaufanych danych.
Recommendation
Zaleca się monitorowanie i aktualizację urządzeń pamięci masowej, aby zapewnić, że są one zgodne z najnowszymi standardami bezpieczeństwa. Należy również rozważyć wdrożenie dodatkowych mechanizmów zabezpieczających w celu ochrony przed potencjalnymi atakami na protokół RPMB.

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)
Western Digital has identified a security vulnerability in the Replay Protected Memory Block (RPMB) protocol as specified in multiple standards for storage device interfaces, including all versions of eMMC, UFS, and NVMe. The RPMB protocol is specified by industry standards bodies and is implemented by storage devices from multiple vendors to assist host systems in securing trusted firmware. Several scenarios have been identified in which the RPMB state may be affected by an attacker without the knowledge of the trusted component that uses the RPMB feature.
