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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: 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 impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Jan 2024
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 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

Upgrade Hitachi Device Manager to 8.8.5-04.

AI-suggested

To mitigate CVE-2023-49107, European organizations should: 1) Immediately verify the version of Hitachi Device Manager in use and plan to upgrade to version 8.8.5-04 or later once available, as this is the fixed version addressing the vulnerability. 2) Until patches are available, restrict network access to the Device Manager Agent modules by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3) Monitor logs and error messages for unusual or verbose outputs that may indicate exploitation attempts or information leakage. 4) Employ application-layer filtering or proxy solutions to sanitize error messages if feasible, preventing sensitive data from being exposed externally. 5) Conduct internal security assessments and penetration tests focusing on error handling and information disclosure in Hitachi Device Manager deployments. 6) Maintain up-to-date incident response plans that include procedures for handling information disclosure vulnerabilities. 7) Engage with Hitachi support channels to receive timely updates and patches. These steps go beyond generic advice by focusing on immediate containment, monitoring, and preparation for patch deployment.

Description

Generation of Error Message Containing Sensitive Information vulnerability in Hitachi Device Manager on Windows, Linux (Device Manager Agent modules).This issue affects Hitachi Device Manager: before 8.8.5-04.

Impact

For European organizations using Hitachi Device Manager, this vulnerability poses a risk primarily to confidentiality. Disclosure of sensitive information through error messages can aid attackers in mapping the environment, identifying system configurations, or uncovering other exploitable details. Although the vulnerability does not directly compromise system integrity or availability, the leaked information could be used as a stepping stone for more sophisticated attacks, such as targeted intrusions or lateral movement within networks. Organizations in sectors with high regulatory requirements for data protection, such as finance, healthcare, and critical infrastructure, may face compliance risks if sensitive information is exposed. Additionally, the cross-platform nature of the vulnerability (Windows and Linux) increases the attack surface. Given the lack of known exploits, the immediate risk is moderate, but the potential for exploitation remains, especially if attackers develop proof-of-concept code. European entities relying on Hitachi Device Manager for device and storage management should consider this vulnerability seriously due to the potential for information leakage that could undermine security postures.

CWE-209Generation of Error Message Containing Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product generates an error message that includes sensitive information about its environment, users, or associated data.
Implementation
Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended).
Implementation
Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
Implementation · Attack Surface Reduction
Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
