CVE-2021-32543
After login, remote attackers can manipulate cookies to access other accounts and trade in the stock market with spoofed identity.
Does this matter?
Lower severity and a low EPSS score (0.76%). Track it; it rarely justifies an emergency change on its own.
Description
The CTS Web transaction system related to authentication management is implemented incorrectly. After login, remote attackers can manipulate cookies to access other accounts and trade in the stock market with spoofed identity.
