CVE-2019-6819
HighSummary
Istnieje podatność CWE-754: Niewłaściwe sprawdzenie nietypowych lub wyjątkowych warunków, która może prowadzić do potencjalnego ataku typu Denial of Service, gdy do kontrolera wysyłane są określone ramki Modbus w produktach: Modicon M340 - wersje oprogramowania przed V3.01, Modicon M580 - wersje oprogramowania przed V2.80, wszystkie wersje oprogramowania Modicon Quantum i Modicon Premium.
Risk Assessment
Podatność ta może prowadzić do zakłócenia działania systemów, co w konsekwencji może wpłynąć na dostępność usług w organizacji.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, aby zniwelować ryzyko związane z tą podatnością.

A vulnerability was identified in FAST FAC1900R version 20190827_2.0.2.2 in the copy_msg_element function of the devdiscover Service component. Manipulation leads to a stack-based buffer overflow, and the attack can be executed remotely. The exploit is publicly available and may be used; the vendor did not respond to the disclosure.
- CVE-2026-101038Critical
A vulnerability was determined in FAST FAC1200R version 5.0_20201119_1.0.2 in the MmtAtePrase function of the MmtAtePrase Parser component. Manipulation causes a stack-based buffer overflow, and remote exploitation is possible. The exploit has been publicly disclosed and may be utilized; the vendor did not respond to the disclosure.
- CVE-2026-101037Critical
A vulnerability was found in FAST FAC1200R version 5.0_20201119_1.0.2 in the parse_advertisement_frame function of the devdiscover Service component. Manipulation results in a stack-based buffer overflow, and the attack may be launched remotely. The exploit has been made public and could be used; the vendor did not respond to the disclosure.
- CVE-2026-82384Critical
Apache Roller 6.1.5 contains a Deserialization of Untrusted Data vulnerability because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication. The servlet is mapped unconditionally, so parsing occurs even when the global XML-RPC feature is disabled; no non-default configuration is required. This can lead to remote code execution.
- CVE-2026-82378Critical
Apache Roller 6.1.5 contains an Incorrect Authorization vulnerability in the OAuth 1.0a authorization endpoint. An unauthenticated remote attacker who learns an outstanding request token for a configured site-wide consumer can bind that token to an arbitrary user account, including an administrator, by submitting an unsigned authorization request. The endpoint derives the authorizing identity from a request-supplied value rather than the authenticated session.
- CVE-2026-82377Critical
Apache Roller 6.1.5 contains a Missing Authorization vulnerability that allows an authenticated user to read, modify, or delete weblog content belonging to other weblogs through the legacy XML-RPC Blogger and MetaWeblog APIs. The handlers authenticate the caller but do not verify the caller's permission on the weblog or entry actually affected. Only installations that enable the non-default global XML-RPC setting are affected; the per-weblog API flag defaults to enabled for UI-created weblogs.
- CVE-2026-101008Critical
A vulnerability was found in aaPanel BaoTa up to version 11.8.0 in the merge_split_file function of the file /www/server/panel/class/files.py in the File Merge Handler component. Manipulation of the split_file_path argument results in command injection, and the attack can be carried out remotely. The exploit has been made public and could be used; the vendor did not respond to the disclosure.
- CVE-2026-101002Critical
A security flaw was discovered in Netcore NBR200V2 version 1.3.241127.071246. Manipulation of the url argument in the system function of /usr/bin/network_tools within the Tools Ping Handler component results in OS command injection. The attack can be initiated remotely and the exploit has been publicly released.
