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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

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

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

NAKIVO Backup & Replication before 11.0.0.88174 allows absolute path traversal for reading files via getImageByPath to /c/router (this may lead to remote code execution across the enterprise because PhysicalDiscovery has cleartext credentials).

Impact

The vulnerability allows unauthenticated remote attackers to read arbitrary files on systems running vulnerable versions of NAKIVO Backup & Replication Director. This can lead to disclosure of sensitive information, including cleartext credentials used by the PhysicalDiscovery component. Such credential exposure can facilitate lateral movement, privilege escalation, and potentially remote code execution within enterprise networks. The compromise of backup infrastructure is particularly severe as it may allow attackers to manipulate or destroy backup data, undermining disaster recovery capabilities. Enterprises relying on NAKIVO for backup and replication are at risk of data breaches, operational disruption, and loss of trust. The high CVSS score reflects the ease of exploitation and the critical confidentiality impact, making this a significant threat to organizations worldwide that use this product.

Mitigation

1. Immediately upgrade NAKIVO Backup & Replication Director to version 11.0.0.88174 or later once the patch is available. 2. Until patching is possible, restrict network access to the Backup & Replication Director interface, limiting it to trusted management networks only. 3. Implement strict firewall rules and network segmentation to isolate backup infrastructure from general enterprise networks and the internet. 4. Monitor logs and network traffic for suspicious access patterns to the getImageByPath endpoint or unusual file read requests. 5. Rotate any credentials stored or used by the PhysicalDiscovery component to mitigate risks from potential credential exposure. 6. Employ application-layer firewalls or web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting the vulnerable endpoint. 7. Conduct regular security audits and vulnerability scans on backup infrastructure to detect similar issues proactively. 8. Educate IT and security teams about the risks of path traversal vulnerabilities and the importance of securing backup systems.

CWE-36Absolute Path Traversal (opens in a new tab)
Base weaknessOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
Operation · Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
