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: 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

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Aug 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 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.

AI-suggested

1. Implement input sanitization and validation on all user-supplied data that is exported to CSV files, ensuring that any fields starting with characters like '=', '+', '-', or '@' are either escaped or prefixed with a single quote to neutralize formula execution. 2. Restrict access to the exportOrder function to authorized users only, applying strict access controls and monitoring usage logs for suspicious activity. 3. Educate users about the risks of opening CSV files from untrusted sources and encourage the use of spreadsheet software settings that disable automatic formula execution or enable protected view modes. 4. Employ network-level controls to limit exposure of the vulnerable endpoint, such as IP whitelisting or VPN access. 5. Monitor for any unusual CSV export patterns or anomalies that could indicate exploitation attempts. 6. Consider implementing application-layer firewalls or runtime application self-protection (RASP) solutions to detect and block injection attempts. 7. If feasible, review and modify the source code to sanitize output or switch to safer export formats that do not support formula execution. 8. Maintain an incident response plan to quickly address any detected exploitation or data compromise related to this vulnerability.

Description

A vulnerability was found in xujeff tianti 天梯 up to 2.3. It has been rated as problematic. This issue affects the function exportOrder of the file /tianti-module-admin/user/ajax/save of the component com.jeff.tianti.controller. The manipulation leads to csv injection. The attack may be initiated remotely. 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 using xujeff tianti 天梯, this vulnerability poses a moderate risk. The ability to inject malicious formulas into CSV exports can lead to unauthorized data access or manipulation when files are opened in spreadsheet applications. This can compromise sensitive business data, financial records, or user information, potentially violating GDPR requirements on data protection and privacy. The remote exploitability without user interaction or authentication increases the risk in automated or bulk export scenarios. Organizations relying on tianti 天梯 for order management or administrative functions may face operational disruptions or reputational damage if CSV Injection is exploited. Additionally, the lack of vendor response and patches means organizations must proactively mitigate the risk. The medium severity score reflects the moderate impact on confidentiality and integrity, with limited impact on availability. However, if attackers leverage this vulnerability as part of a broader attack chain, the consequences could escalate.
