TYPO3 CVE-2019-19849 Multiple Remote Code Execution Vulnerabilities

Description

TYPO3 is prone to multiple remote code-execution vulnerabilities. Successfully exploiting these issues allows attackers to execute arbitrary code in the context of the affected application. Failed exploits will result in denial-of-service conditions. Versions prior to TYPO3 8.7.30, 9.5.12 and 10.2.2 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Updates are available. Please see the references or vendor advisory for more information.
