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: 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 on the impacted component.
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 impacted component 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 impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 7 Jul 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 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 Nimesa Backup and Recovery to 3.0.2025062305.

AI-suggested

To mitigate this vulnerability, European organizations should prioritize upgrading Nimesa Backup and Recovery to version 3.0.2025062305 or later, where the SSRF flaw is addressed. In addition to patching, organizations should implement strict network segmentation and firewall rules to limit the backup server's ability to initiate arbitrary outbound requests, especially to sensitive internal services. Monitoring and logging outbound requests from backup systems can help detect anomalous activity indicative of exploitation attempts. Employing web application firewalls (WAFs) with SSRF detection capabilities can provide an additional layer of defense. Furthermore, organizations should review and harden the configuration of Nimesa Backup and Recovery, disabling any unnecessary features that could be exploited. Regular security assessments and penetration testing focusing on backup infrastructure can help identify and remediate related risks proactively.

Description

Server-side request forgery (SSRF) vulnerability exists n multiple versions of Nimesa Backup and Recovery, If this vulnerability is exploited, unintended requests may be sent to internal servers.

Impact

For European organizations, the impact of this SSRF vulnerability in Nimesa Backup and Recovery could be substantial. Backup and recovery systems often have privileged access to sensitive data and internal networks, making them high-value targets. Exploitation could lead to unauthorized access to internal services, exposing confidential data or enabling lateral movement within the network. This could compromise data integrity and availability, potentially disrupting business continuity and recovery processes. Given the GDPR and other stringent data protection regulations in Europe, any data breach resulting from this vulnerability could also lead to significant regulatory penalties and reputational damage. Organizations relying on Nimesa Backup and Recovery must consider the risk of internal network exposure and the potential for attackers to use this SSRF as a foothold for further attacks.
