Unauthenticated Oracle Secure Backup Flaw Rated Critical with CVSS 9.8
A newly disclosed vulnerability in Oracle Secure Backup allows network-based attackers to fully compromise the system without credentials.
Key points
- CVE-2026-101484 affects Oracle Secure Backup versions 19.1.0.0.0 and 19.1.0.1.0.
- The flaw carries a CVSS 3.1 Base Score of 9.8, classified as Critical.
- Attackers require only network access via TCP to exploit the issue remotely.
The National Vulnerability Database has recorded CVE-2026-101484, a critical security flaw in Oracle Secure Backup. This vulnerability allows unauthenticated attackers with network access to fully compromise the backup system. The issue resides within the Backup and Restore component of the software.
According to the NVD record, the flaw is rated 9.8 on the CVSS 3.1 scale. This score reflects high impacts on confidentiality, integrity, and availability. The vector string indicates that exploitation requires no user interaction and no prior authentication privileges. Attackers can leverage standard TCP network access to trigger the compromise.
Context and Background
The vulnerability is described as easily exploitable by remote adversaries. An attacker does not need valid credentials to initiate the attack sequence. Instead, they need only network connectivity to the affected Oracle Secure Backup instance. The NVD entry specifies that the attack complexity is low, further elevating the risk profile.
Successful exploitation results in the complete takeover of the Oracle Secure Backup system. This means an attacker gains control over the backup infrastructure. The CVSS metrics assign high scores to confidentiality, integrity, and availability impacts. This suggests that data loss, manipulation, or service disruption are likely outcomes of a successful attack.
Who Is Affected
Only specific versions of Oracle Secure Backup are confirmed to be vulnerable. The NVD record lists version 19.1.0.0.0 as affected. Version 19.1.0.1.0 is also listed as supported and affected by this flaw. Organizations running these specific releases are exposed to the risk of remote compromise.
Other versions of Oracle Secure Backup are not mentioned in the current NVD entry. Users should verify their installed version against the affected list. The component identified in the record is Backup and Restore. This component is central to the software's primary function, increasing the potential impact of any breach.
What should you do?
Security teams should immediately audit their environments for the affected versions. Identifying instances of Oracle Secure Backup 19.1.0.0.0 and 19.1.0.1.0 is the first step. Network segmentation can limit access to the backup servers. Restricting TCP traffic to trusted sources reduces the attack surface.
What to do and how to stay safe: Oracle
- Inventory all Oracle Secure Backup installations to identify versions 19.1.0.0.0 and 19.1.0.1.0.
- Restrict network access to backup servers using firewalls or network segmentation.
- Monitor logs for unauthorized connection attempts or unusual activity on TCP ports.
- Prepare to isolate affected systems if exploitation is suspected, pending vendor guidance.
