| CVE-2022-24682 | Zimbra Webmail Cross-Site Scripting Vulnerability | secondary_impact | T1185 | Browser Session Hijacking |
Comments
This vulnerability is exploited by an attacker via spear-phishing emails containing malicious links to inject arbitrary HTML and JavaScript into the document by placing executable JavaScript inside element attributes. This results in unescaped markup, enabling the attacker to execute JavaScript in the context of a user's Zimbra session, leading to potential data theft and other malicious activities.
This vulnerability was identified by Volexity in December 2021 during a series of targeted spear-phishing campaigns conducted by a threat actor tracked as TEMP_Heretic. The campaigns aimed to exploit this zero-day vulnerability, allowing attackers to execute arbitrary JavaScript in the context of a user's Zimbra session.
The attack involved two phases: an initial reconnaissance phase using emails with embedded remote images to track if targets opened the messages, and a second phase with spear-phishing emails containing malicious links. If a target clicked on these links while logged into the Zimbra webmail client, the attacker could exploit the vulnerability to steal email data and attachments.
