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

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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

To mitigate CVE-2026-2864, organizations should implement multiple layers of defense: 1) Apply strict input validation and sanitization on the picName parameter to prevent directory traversal sequences (e.g., ../) from being processed. 2) Enforce the principle of least privilege by restricting file system permissions for the ERP application user, ensuring it cannot delete or modify files outside designated directories. 3) Implement application-level allowlisting for file operations to restrict deletions to known safe paths. 4) Monitor logs and file system activity for unusual deletion patterns or access attempts indicative of exploitation. 5) If possible, isolate the ERP application in a sandboxed environment or container to limit the blast radius of any successful attack. 6) Engage with the vendor or community to track patch releases or updates addressing this vulnerability. 7) As a temporary measure, consider disabling or restricting access to the pictureDelete function if it is not essential. 8) Conduct regular backups of ERP data and configuration files to enable recovery in case of file deletion. 9) Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attack patterns targeting picName parameters.

Description

A vulnerability has been found in feng_ha_ha/megagao ssm-erp and production_ssm up to 4288d53bd35757b27f2d070057aefb2c07bdd097. This affects the function pictureDelete of the file PictureController.java. Such manipulation of the argument picName leads to path traversal. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. This product is distributed under two entirely different names. The project was informed of the problem early through an issue report but has not responded yet.

Impact

The path traversal vulnerability in ssm-erp can have significant impacts on organizations relying on this ERP system. Unauthorized deletion of files can lead to loss of critical business data, disruption of ERP functionality, and potential downtime affecting business operations. Since ERP systems often manage sensitive financial, inventory, and personnel data, integrity and availability impacts could cascade into operational and compliance risks. Attackers exploiting this vulnerability remotely can cause damage without requiring user interaction, increasing the risk of automated or widespread attacks. The lack of vendor response and absence of patches further exacerbate the risk, leaving organizations exposed. Additionally, the inability to easily identify affected versions complicates incident response and remediation efforts. Organizations may face increased costs related to recovery, forensic analysis, and potential regulatory penalties if sensitive data is affected.

Summary

CVE-2026-2864 is a path traversal vulnerability identified in the ssm-erp software developed by feng_ha_ha, specifically within the pictureDelete function of the PictureController.java file. The vulnerability arises from improper sanitization of the picName parameter, which an attacker can manipulate to traverse directories outside the intended file path. This can lead to unauthorized deletion of arbitrary files on the server hosting the ERP system. The vulnerability can be exploited remotely without user interaction, but requires low-level privileges on the system. The product is distributed under two different names and lacks versioning, making it difficult to determine the full scope of affected versions. The vendor was notified early but has not issued a patch or response. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no user interaction, and limited impact on confidentiality, integrity, and availability. While no known exploits are currently active in the wild, the public disclosure of the exploit code increases the likelihood of exploitation attempts. The vulnerability could allow attackers to delete critical files, potentially disrupting ERP operations and causing data loss or service outages.
