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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Jan 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), 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

To mitigate CVE-2024-53935, users and organizations should first verify if the affected application (iCall OS17 - Color Phone Flash) is installed on their Android devices and update it to a patched version once available. In the absence of an official patch, consider uninstalling or disabling the app to eliminate the attack vector. Employ mobile device management (MDM) solutions to restrict installation of untrusted or unnecessary applications, reducing the risk of malicious apps exploiting this vulnerability. Monitor device behavior for unexpected phone call activity, which could indicate exploitation attempts. Developers and vendors should implement proper intent validation and require explicit permissions and user interaction before placing calls. Security teams should educate users about the risks of installing apps from untrusted sources and encourage the use of app stores with rigorous vetting processes. Additionally, applying runtime application self-protection (RASP) or endpoint detection and response (EDR) tools on mobile devices may help detect and block suspicious intent-based activities. Finally, maintain up-to-date threat intelligence to respond promptly when patches or exploit reports emerge.

Description

The com.callos14.callscreen.colorphone (aka iCall OS17 - Color Phone Flash) application through 4.3 for Android enables any application (with no permissions) to place phone calls without user interaction by sending a crafted intent via the com.callos14.callscreen.colorphone.DialerActivity component.

Impact

The primary impact of CVE-2024-53935 is unauthorized phone call initiation without user consent, which can lead to financial loss due to premium-rate calls, privacy violations, and potential harassment or social engineering attacks. Organizations relying on Android devices with this app installed may face increased risk of fraud or abuse, especially if devices are used in sensitive environments or by employees handling confidential information. The vulnerability could be exploited to bypass security controls that rely on user interaction or permission checks, undermining trust in mobile device security. Although availability is not affected, the integrity and confidentiality of user communications are compromised. The ease of exploitation (no permissions or user interaction required) increases the likelihood of abuse if a malicious app is installed on the device. This could also facilitate broader attacks if combined with other vulnerabilities or social engineering tactics. The lack of known exploits in the wild suggests limited current impact, but the potential for future exploitation remains significant.
