Attackers can send a crafted ACTION_SEND intent with a _display_name containing directory traversal sequences to overwrite sensitive files within the app's sandbox such as databases, shared_prefs, and WebView data, enabling state tampering or code execution in the app's context without authentication or user interaction.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/actuator/com.alanmobile","tags":[]},{"url":"https://play.google.com/store/apps/details?id=com.alanmobile","tags":[]},{"url":"https://www.vulncheck.com/advisories/alan-health-insurance-for-android-path-traversal-via-sharereceiveractivity","tags":[]}],"exploitRefs":[{"url":"https://github.com/actuator/com.alanmobile","tags":[]}],"hasPoc":true,"ai":null}
