Despite a coordinated investment of time, effort, planning, and resources, even the most up-to-date cybersecurity systems continue to fail. Every day. Why? It’s not because security teams can't see enough. Quite the contrary. Every security tool spits out thousands of findings. Patch this. Block that. Investigate this. It's a tsunami of red dots that not even the most crackerjack team on
What happens when you bring in a team of cybersecurity responders? How do we turn chaos into control, and what is the long-term value that Talos IR provides to the organizations we work with?
### Impact It is possible for a remote unauthenticated user to escape from the HQL execution context and perform a blind SQL injection to execute arbitrary SQL statements on the database backend, including when "Prevent unregistered users from viewing pages, regardless of the page rights" and "Prevent unregistered users from editing pages, regardless of the page rights" options are enabled. Depending on the used database backend, the attacker may be able to not only obtain confidential information such as password hashes from the database, but also execute UPDATE/INSERT/DELETE queries. The vulnerability may be tested in a default installation of XWIki Standard Flavor, including using the official Docker containers. An example query, which leads to SQL injection with MySQL/MariaDB backend is shown below: ``` time curl "http://127.0.0.1:8080/rest/wikis/xwiki/query?q=where%20doc.name=length('a')*org.apache.logging.log4j.util.Chars.SPACE%20or%201%3C%3E%271%5C%27%27%20union%20select%20...
Thorsten picks apart some headlines, highlights Talos’ report on an unknown attacker predominantly targeting Japan, and asks, “Where is the victim, and does it matter?”
From zero-day exploits to 5G network vulnerabilities, these are the threats that are expected to persist over the next 12 months.
During holidays and slow weeks, teams thin out and attackers move in. Here are strategies to bridge gaps, stay vigilant, and keep systems secure during those lulls.
We can anticipate a growing number of emerging vulnerabilities in the near future, emphasizing the need for an effective prioritization strategy.
Apache ActiveMQ Artemis allows access to diagnostic information and controls through MBeans, which are also exposed through the authenticated Jolokia endpoint. Before version 2.29.0, this also included the Log4J2 MBean. This MBean is not meant for exposure to non-administrative users. This could eventually allow an authenticated attacker to write arbitrary files to the filesystem and indirectly achieve RCE. Users are recommended to upgrade to version 2.29.0 or later, which fixes the issue.
A researcher claims to have found a decade-old vulnerability rated 9.9 that affects all GNU/Linux systems, allowing attackers…
It shouldn’t just be viewed as a cybersecurity issue, because for a hardware supply chain attack, an adversary would likely need to physically infiltrate or tamper with the manufacturing process.
