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: 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within 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

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.

AI-suggested

Immediately restrict external access to the /jshERP-boot/plugin/uploadPluginConfigFile endpoint via network controls such as firewalls or web application firewalls (WAFs) to limit exposure.
Implement strict input validation and sanitization on the configFile parameter to prevent directory traversal sequences (e.g., ../).
Employ least privilege principles for the jshERP application process to minimize file system access rights, limiting the impact of potential exploitation.
Monitor logs for suspicious requests targeting the vulnerable endpoint, especially those containing traversal patterns.
If possible, deploy virtual patching through WAF rules that detect and block path traversal attempts.
Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability.
Consider isolating the jshERP instance in a segmented network zone to reduce potential lateral movement.
Regularly back up critical data and configurations to enable recovery in case of compromise.
Educate system administrators about this vulnerability and ensure timely application of any future patches.

Description

A vulnerability was identified in jishenghua jshERP up to 3.6. Affected by this vulnerability is an unknown functionality of the file /jshERP-boot/plugin/uploadPluginConfigFile of the component PluginController. Such manipulation of the argument configFile leads to path traversal. The attack may be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.

Impact

The primary impact of this vulnerability is unauthorized disclosure of sensitive information due to path traversal, which can compromise confidentiality. Attackers can read arbitrary files on the affected server, potentially exposing credentials, configuration details, or other sensitive data. This exposure can lead to further exploitation, including privilege escalation or lateral movement within an organization's network. Since the vulnerability is remotely exploitable without authentication or user interaction, it poses a significant risk to any organization using affected versions of jshERP, especially those exposing the vulnerable endpoint to untrusted networks. The lack of vendor response and patch availability increases the window of exposure. Organizations in sectors relying heavily on jshERP for enterprise resource planning may face operational disruptions, data breaches, and compliance violations if exploited.

Summary

CVE-2026-1549 is a path traversal vulnerability discovered in the jishenghua jshERP product, affecting all versions up to 3.6. The vulnerability resides in the PluginController component, specifically within the /jshERP-boot/plugin/uploadPluginConfigFile endpoint. The issue arises from insufficient validation or sanitization of the configFile parameter, which an attacker can manipulate to traverse directories on the server's filesystem. This allows unauthorized access to files outside the intended directory scope. The vulnerability can be exploited remotely over the network without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 5.3, reflecting medium severity, with the vector indicating network attack vector, low attack complexity, no privileges required, no user interaction, and limited confidentiality impact. Although no patches have been released and the vendor has not responded to the issue report, a public exploit exists, making timely mitigation critical. The vulnerability could lead to unauthorized disclosure of sensitive files such as configuration files, credentials, or other critical data stored on the server, potentially facilitating further attacks or system compromise.
