CVE-2023-1714
Unsafe variable extraction in bitrix/modules/main/classes/general/user_options.php in Bitrix24 22.0.300 allows remote authenticated attackers to execute arbitrary code via (1) appending arbitrary content to existing PHP files or (2) PHAR deserialization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
