Several IT security companies were able to spot exploitation of a zero-day vulnerability in Adobe Flash Player against users in the Middle East.
According to published details, the attackers used a phishing attack pretending to be a popular job search website. The majority of the targeted users are in Doha and Qatar. The attack was detected on June 1, 2018.
The vulnerability in question used by the attackers is CVE-2018-5002. The exploit was delivered to users via an Excel file named “salary.xls”. The file by itself did not contain the exploit, instead, once opened, it was trying to download it.
Adobe reacted to issue very quickly and released today a security patch with version 220.127.116.11. Please, update ASAP.
This is the third zero-day vulnerability in Adobe products this year. The first vulnerability this year was also discovered in Adobe Flash (CVE-2018-4878). The second one CVE-2018-4990 was reported by ESET in Adobe Reader and fixed less than a month ago.
