In its advisory, the NSA supplied additional particulars on the vulnerability in Exim that Sandworm is actively exploiting, saying:
“The vulnerability being exploited, CVE-2019-10149, permits a distant attacker to execute instructions and code of their selecting.

Whereas the NSA didn’t reveal who the Russian army hackers have focused, in latest months senior US intelligence officers have warned that Kremlin brokers are presently engaged in actions on-line that would threaten the integrity of the nation’s 2020 presidential election.
Organizations and authorities companies that use Exim ought to apply this patch instantly in the event that they haven’t already accomplished so to keep away from falling sufferer to any potential assaults.
