CVE-2020-15798
CriticalCVSS 9.8Summary
Zidentyfikowano podatność w panelach HMI Comfort SIMATIC (w tym warianty SIPLUS) oraz w różnych modelach SINAMICS, które mają włączoną usługę telnet. Urządzenia te nie wymagają uwierzytelnienia dla tej usługi, co może umożliwić zdalnemu atakującemu uzyskanie pełnego dostępu do urządzenia.
Risk Assessment
Brak uwierzytelnienia dla usługi telnet stwarza poważne ryzyko, ponieważ atakujący może zdalnie przejąć kontrolę nad urządzeniem, co może prowadzić do zakłóceń w działaniu systemów przemysłowych.
Recommendation
Zaleca się wyłączenie usługi telnet na podatnych urządzeniach oraz aktualizację oprogramowania do wersji V16 Update 3a lub nowszej, aby zminimalizować ryzyko ataku.

MaxSite CMS through 109.6 ships with a hardcoded session encryption key in application/config/config.php that is never changed during installation, allowing unauthenticated attackers to forge administrator session cookies. Attackers can mint a malicious ci_session cookie with administrator privileges by computing an HMAC-SHA1 using the publicly known encryption key, bypassing authentication checks in is_login() and mso_check_allow() functions.
- CVE-2026-47156Critical
MantisBT versions 2.28.3 and earlier contain a critical authentication bypass in the SOAP API's mci_check_login() function. Any user knowing any valid cookie_string can authenticate as any other user (knowing their username), including the administrator, without knowing the target's password. The vulnerability is exploitable with zero prior access on default installations because self-registration is enabled by default.
- CVE-2026-68484Critical
Cash Collect contains an improper authorization vulnerability in the Sage AR Automation API. Administrative functions do not properly verify user privileges, allowing authenticated low-privileged users to create administrator accounts and obtain elevated privileges.
- CVE-2026-67403Critical
Cash Collect contains an improper authorization vulnerability in the Sage AR Automation API. Insufficient tenant-level authorization checks allow authenticated users to access administrative resources belonging to other tenants by specifying a valid non predictable tenant identifier.

- CVE-2026-22590Critical
eprosima Fast DDS versions prior to 2.6.12, 2.14.6, 3.2.4, 3.3.1, and 3.4.2 have a remotely triggerable Out-of-Bounds Read while processing RTPS DATA_FRAG submessages. An attacker can craft a DATA_FRAG with a large sampleSize but a small actual payload, leading to reading past the received UDP datagram buffer and copying adjacent heap memory into the reassembly buffer.
- CVE-2026-85103Critical
A heap-based buffer overflow in VPN certificate ASN.1 decoding may allow an unauthenticated remote attacker to execute arbitrary code on Check Point Quantum Security Management and Quantum Security Gateway systems.
- CVE-2026-85102Critical
Improper certificate trust validation during VPN negotiation in Check Point Quantum Security Gateway may allow an unauthenticated remote attacker to execute arbitrary code on the Gateway.
- CVE-2026-80172Critical
Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00 contain an Insufficient Verification of Data Authenticity vulnerability. An unauthenticated attacker with remote access could exploit this, leading to unauthorized access. The attacker can repeatedly reuse a captured request to generate ADMIN access and refresh tokens without nonce validation or time limits.
- CVE-2026-87827Critical
Certain KGUARD DVR devices running vulnerable firmware expose a system command execution service on all network interfaces without requiring authentication. A remote unauthenticated attacker can execute arbitrary system commands, potentially leading to complete compromise. Exploited by Mirai_ptea and Mirai_aurora botnets for malware propagation and DDoS.
Original NVD description (English source)
A vulnerability has been identified in SIMATIC HMI Comfort Panels (incl. SIPLUS variants) (All versions < V16 Update 3a), SIMATIC HMI KTP Mobile Panels (All versions < V16 Update 3a), SINAMICS GH150 (All versions), SINAMICS GL150 (with option X30) (All versions), SINAMICS GM150 (with option X30) (All versions), SINAMICS SH150 (All versions), SINAMICS SL150 (All versions), SINAMICS SM120 (All versions), SINAMICS SM150 (All versions), SINAMICS SM150i (All versions). Affected devices with enabled telnet service do not require authentication for this service. This could allow a remote attacker to gain full access to the device. (ZDI-CAN-12046)
