1 minute read
Speak With A Security Expert Now

A vulnerability affecting Oracle Database Servers has been identified and could allow a remote attacker to take complete control of the affected system. After establishing control over the affected system, the threat actor may also gain shell access to the underlying server [1]. This vulnerability is being tracked as CVE-2018-3110 and security patches have been made available by Oracle [2]. At the time of publishing, it is not believed that CVE-2018-3110 has been exploited in the wild, but the low level of complexity along with high severity would make this an attractive target for threat actors. eSentire Threat Intelligence assesses with medium confidence that this vulnerability will be weaponized quickly and affected systems should be patched as soon as possible.
