Availability: Low

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Jul 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

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 2026-10-26.

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 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 SYNCK GRAPHICA Real-time Bus Tracking System to 1.1.

AI-suggested

To mitigate this vulnerability, European organizations should prioritize upgrading the SYNCK GRAPHICA Real-time Bus Tracking System to version 1.1 or later once available. If you cannot patch yet, organizations should enforce strict access controls to the administrative interface, including multi-factor authentication (MFA) and monitoring of administrative login activities to detect suspicious behavior. Network segmentation should be applied to isolate the administrative interface from general network access, limiting exposure. Input validation mechanisms should be reviewed and enhanced to prevent improper quantity inputs, potentially through custom validation rules or web application firewalls (WAFs) that can detect and block malformed requests. Regular security audits and penetration testing focusing on administrative interfaces are recommended to identify similar issues proactively. Finally, organizations should prepare incident response plans to quickly address potential DoS conditions affecting the bus tracking system.

Description

Improper validation of specified quantity in input issue exists in Real-time Bus Tracking System versions prior to 1.1. If exploited, a denial of service (DoS) condition may be caused by an attacker who can log in to the administrative page of the affected product.

Impact

For European organizations, particularly public transportation authorities and companies using the SYNCK GRAPHICA Real-time Bus Tracking System, this vulnerability could lead to service interruptions. A denial of service attack could prevent the system from providing accurate real-time bus location data, affecting route management, scheduling, and passenger information services. This disruption could degrade public trust and operational efficiency, especially in urban areas with high reliance on public transit. Additionally, since the vulnerability requires administrative access, insider threats or compromised administrative credentials could be exploited, increasing risk. The impact is primarily operational but could cascade into economic losses and reputational damage for transit operators. Given the increasing digitization of public transport infrastructure in Europe, such vulnerabilities could also attract attention from threat actors aiming to cause disruption or test resilience of critical infrastructure.
