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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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 31 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

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 Apache ServiceComb Service-Center to 2.2.0.

AI-suggested

European organizations should prioritize upgrading Apache ServiceComb Service-Center to version 2.2.0 or later to remediate this vulnerability. Beyond patching, organizations should implement strict network segmentation and firewall rules to restrict access to the Service-Center management interfaces, ensuring they are not exposed to public or untrusted networks. Employing strong authentication and authorization mechanisms around service governance tools can further reduce risk. Regularly auditing access logs and monitoring for unusual access patterns to the Service-Center can help detect potential exploitation attempts early. Additionally, organizations should review and minimize the sensitive information stored or accessible via Service-Center to reduce the impact of any potential leaks. Incorporating these controls into a broader microservices security strategy will enhance resilience against similar vulnerabilities.

Description

Exposure of Sensitive Information to an Unauthorized Actor in Apache ServiceComb Service-Center.This issue affects Apache ServiceComb Service-Center before 2.1.0 (include). Users are recommended to upgrade to version 2.2.0, which fixes the issue.

Impact

For European organizations utilizing Apache ServiceComb Service-Center in their microservices architecture, this vulnerability poses a tangible risk of unauthorized disclosure of sensitive configuration or operational data. Such exposure could include service metadata, credentials, or internal network information, which attackers could leverage to map the infrastructure or escalate attacks. This risk is particularly significant for sectors with stringent data protection requirements such as finance, healthcare, and critical infrastructure, where leakage of sensitive information could lead to regulatory penalties under GDPR and damage to reputation. The vulnerability’s ease of exploitation (no authentication or user interaction required) increases the likelihood of opportunistic attacks, especially in environments where Service-Center is exposed to untrusted networks. However, the lack of impact on integrity and availability limits the immediate operational disruption, focusing the threat primarily on confidentiality breaches.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
