Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable system. Physical interaction may be brief (e.g., evil maid attack) or persistent.
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

CVE published 27 Jun 2025
Detectable: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Users should immediately update the Bharti Airtel Thanks App once a patched version is released by the vendor.
Until a patch is available, users should avoid storing sensitive information within the app or on devices that may be physically accessible to unauthorized persons.
Employ device-level encryption and strong lock screen protections (PIN, biometric) to reduce the risk of unauthorized physical access to the device's file system.
Organizations should implement mobile device management (MDM) solutions that enforce encryption, remote wipe capabilities, and restrict installation of vulnerable apps on corporate devices.
Regularly audit devices for the presence of vulnerable app versions and remove or update them accordingly.
Educate users about the risks of physical device compromise and encourage secure handling of devices, especially when traveling or in public spaces.
Monitor for any updates or advisories from Bharti Airtel regarding this vulnerability and apply patches promptly.
If possible, avoid using the affected app on devices that contain sensitive corporate data until the vulnerability is addressed.

Description

A vulnerability classified as problematic has been found in Bharti Airtel Thanks App 4.105.4 on Android. Affected is an unknown function of the file /Android/data/com.myairtelapp/files/. The manipulation leads to cleartext storage in a file or on disk. It is possible to launch the attack on the physical device. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, the direct impact of this vulnerability is limited because the Bharti Airtel Thanks App is primarily targeted at the Indian market and its customers. However, if any European entities use this app or if employees traveling from Europe use devices with this app installed, there is a risk of sensitive data exposure through physical device compromise. The vulnerability could lead to leakage of user data stored by the app, which might include personal information or authentication tokens, potentially facilitating further attacks or identity theft. The impact on confidentiality is moderate if sensitive data is stored unencrypted, but the integrity and availability impacts are negligible. Given the requirement for physical access, the threat is more relevant in scenarios where devices might be lost, stolen, or accessed by unauthorized personnel. European organizations with employees who use this app on corporate or personal devices should be aware of the risk of data leakage. Overall, the threat is low for most European organizations but could be a concern for individuals or entities with direct exposure to the affected app.
