Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: 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: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system 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 Vulnerable System 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 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

Exploitation evidence

Disclosed: evidence found.
CVE published 29 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
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), 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.

What to do

AI-suggested

Immediate mitigation should include restricting access to the vulnerable removeFileByPath function to trusted and authenticated users only, minimizing the risk of unauthorized invocation.
Implement strict input validation and sanitization on the 'carimg' parameter to ensure that path traversal sequences (e.g., '../') are detected and blocked.
Employ a whitelist approach for file paths or filenames allowed for deletion, limiting operations strictly to intended directories.
Monitor and audit file deletion operations and logs for suspicious activity indicative of exploitation attempts.
Isolate the application environment using containerization or sandboxing to limit the impact of potential file deletions.
Since the product uses a rolling release strategy, prioritize updating to the latest version once a patch addressing this vulnerability is released.
As a temporary workaround, consider implementing file system permissions that prevent the application user from deleting critical system or configuration files outside the intended directory.
Educate system administrators and security teams about this vulnerability to ensure timely detection and response to any exploitation attempts.

Description

A vulnerability has been found in yeqifu carRental up to 3fabb7eae93d209426638863980301d6f99866b3. This affects the function removeFileByPath of the file src/main/java/com/yeqifu/sys/utils/AppFileUtils.java. The manipulation of the argument carimg leads to path traversal. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used. This product adopts a rolling release strategy to maintain continuous delivery

Impact

For European organizations using yeqifu carRental software, this vulnerability poses a risk of unauthorized file deletion, which can disrupt business operations, cause data loss, and degrade service availability. Organizations in the car rental and fleet management sectors relying on this software could face operational downtime or reputational damage if attackers exploit this flaw to delete critical files or configuration data. The moderate severity suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, it still presents a tangible risk, especially in environments where attackers have limited access or user privileges. Given the remote exploitability, attackers could leverage this vulnerability to escalate their impact within compromised networks. The lack of known exploits in the wild currently reduces immediate risk, but public disclosure increases the likelihood of future exploitation attempts. European organizations should be vigilant, especially those with integrated carRental systems in their IT infrastructure, as disruption to these systems could affect customer service and compliance with data protection regulations if data integrity is compromised.
