[原文]PHP remote file inclusion vulnerability in index.php in one or more ActiveCampaign products, possibly SupportTrio, allows remote attackers to include and execute arbitrary files via the page parameter.
SupportTrio contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker provides malformed input to the 'article' or 'print' variables of the index.php script, which will disclose the software's installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
