DescriptionCVE.org

A vulnerability was detected in myAEDES App up to 1.18.4 on Android. Affected is an unknown function of the file aedes/me/beta/utils/EngageBayUtils.java of the component aedes.me.beta. Performing a manipulation of the argument AUTH_KEY results in information disclosure. The attack is only possible with local access. The attack's complexity is rated as high. The exploitability is told to be difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

A local information disclosure vulnerability exists in myAEDES App versions up to 1.18.4 on Android, stemming from improper handling of the AUTH_KEY argument in the EngageBayUtils.java component. An authenticated local attacker with high complexity can manipulate this parameter to disclose sensitive information, though the attack requires local device access and significant technical effort. …

Vulnerability AssessmentAI

Risk Assessment Despite the low CVSS score of 2.5, this vulnerability presents a nuanced risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with physical access to an unlocked or weakly-protected Android device running myAEDES App can use the public proof-of-concept exploit to manipulate the AUTH_KEY parameter in memory or through local inter-process communication (IPC) mechanisms, causing the EngageBayUtils component to return or log sensitive authentication data such as API keys or bearer tokens. With the extracted credentials, the attacker can then access the EngageBay backend API directly, potentially exfiltrating epidemiological data or personal information handled by the myAEDES application. …
Remediation Upgrade myAEDES App to a version newer than 1.18.4 if available from the vendor or app store. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

During next maintenance window: Apply vendor patches when convenient. …
