Crowdstrike warns that a cyber-criminal group is exploiting CVE-2019-7481 ‘ an older SQL injection vulnerability affecting SonicWall Secure Remote Access (SRA) 4600 devices running firmware versions 8.x and 9.0.x. SonicWall advised customers to upgrade to a newer, supported device line (Secure Mobile Access ‘ SMA) in November 2019. The recommended patch prescribed for SMA devices in 2019, did not fix the flaw in SRA devices. The companies that still run the devices should check which firmware version they are using and check logs for indicators of compromise.
