The Log4j vulnerability, which affects the Java logging framework, has been identified to be susceptible in cloud services like Steam and Apple iCloud, as well as apps like Minecraft.
HIGHLIGHTS
- Digital systems all across the Internet have been affected by a vulnerability in Log4j, a widely used logging framework.
- The logging library vulnerability is simple to exploit, as it allows attackers to take entire control of affected servers.
- Minecraft isn't the only platform affected; the vulnerability in Log4j appears to have infected the whole Java environment.
Examining log files for any services implementing vulnerable Log4j versions might help organisations figure out whether they're affected.
Users should set log4j2.formatMsgNoLookups=True to minimise vulnerabilities by adding "Dlog4j2.formatMsgNoLookups=True" to the JVM command for launching the application.
It is critically advised that Log4j versions be upgraded to log4j-2.15.0-rc1 to prevent the library from being attacked.
