Impact Analysis

Exploitation of this vulnerability can have severe impacts including arbitrary code execution, exposure of sensitive information, denial of service, app malfunction, or failure to launch.

Because the attacker can overwrite internal files, they may inject malicious code or disrupt the normal operation of the app, potentially compromising the device or user data.

The attack requires minimal user interaction and can be triggered automatically when the victim opens the malicious app.

Detection Guidance

Detection of CVE-2025-69618 involves monitoring for suspicious file import activities in the Tarot, Astro & Healing app (version 11.4.0), especially those that attempt path traversal to overwrite internal files.

One approach is to check for unexpected modifications to sensitive internal files such as /data/data/world.eve.coto/shared_prefs/WebViewChromiumPrefs.xml, which can be overwritten by the exploit.

On a rooted Android device or emulator, you can use commands like:

• adb shell ls -l /data/data/world.eve.coto/shared_prefs/WebViewChromiumPrefs.xml
• adb shell stat /data/data/world.eve.coto/shared_prefs/WebViewChromiumPrefs.xml
• adb shell cat /data/data/world.eve.coto/shared_prefs/WebViewChromiumPrefs.xml

Additionally, monitoring app intents with action ACTION_SEND targeting the vulnerable MainActivity for suspicious file URIs with crafted _display_name parameters can help detect exploitation attempts.

Mitigation Strategies

Immediate mitigation steps include:

• Avoid importing files from untrusted sources into the Tarot, Astro & Healing app version 11.4.0.
• Restrict or monitor app permissions that allow file imports or access to internal storage.
• If possible, update the app to a version where this vulnerability is patched.
• Monitor for unusual app behavior such as crashes, failure to launch, or unexpected changes in configuration files.

Since the vulnerability arises from improper validation of imported file paths, applying input validation or sandboxing measures at the app level is recommended once a patch is available.
