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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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 17 Nov 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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.

What to do

Upgrade KDDI 'デジラアプリ' App for iOS to 80.10.00.

AI-suggested

To mitigate this vulnerability, affected users should promptly update the 'デジラアプリ' app to version 80.10.00 or later, where the certificate validation issue is fixed. Organizations should enforce policies requiring up-to-date app versions on employee devices. Network security controls such as enforcing the use of trusted VPNs or secure Wi-Fi can reduce exposure to MITM attacks. Additionally, network monitoring for suspicious SSL/TLS anomalies may help detect attempted exploitation. Developers and security teams should review and strengthen certificate validation logic in mobile applications, employing certificate pinning or robust validation libraries where feasible. User education on avoiding untrusted networks and recognizing suspicious network behavior can further reduce risk. Finally, organizations should consider assessing the necessity of this app within their environment and explore alternatives if risk tolerance is low.

Description

Improper certificate validation vulnerability exists in 'デジラアプリ' App for iOS prior to ver.80.10.00. If this vulnerability is exploited, a man-in-the-middle attack may allow an attacker to eavesdrop on and/or tamper with an encrypted communication.

Impact

For European organizations, the primary impact is the potential compromise of confidentiality and integrity of data transmitted via the 'デジラアプリ' iOS app. Organizations with employees or customers using this app could have sensitive communications intercepted or altered by attackers, especially when connected to insecure networks. This could lead to leakage of proprietary or personal information, undermining trust and potentially violating data protection regulations such as GDPR. While the app's user base in Europe may be limited compared to Japan, multinational companies with Japanese operations or partners may be affected. The lack of availability impact means business continuity is unlikely to be disrupted, but data security and privacy risks remain significant. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure.
