CVE-2026-101483 in Secure Backup
Summary
by MITRE • 10/21/2026
Vulnerability in Oracle Secure Backup (component: Device Management and Support). Supported versions that are affected are 19.1.0.0.0 and 19.1.0.1.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Secure Backup executes to compromise Oracle Secure Backup. While the vulnerability is in Oracle Secure Backup, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Secure Backup. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H).

The identified vulnerability resides within the Device Management and Support component of Oracle Secure Backup, specifically affecting versions 19.1.0.0.0 and 19.1.0.1.0. This flaw represents a significant security risk because it allows for exploitation by an attacker who possesses only low-level privileges on the infrastructure where the software is deployed. The core technical issue involves a condition that leads to resource exhaustion or state corruption, resulting in the application becoming unresponsive or crashing repeatedly. While the immediate impact is confined to Oracle Secure Backup itself, the nature of backup systems means they are often deeply integrated with broader IT infrastructure and critical data repositories. Consequently, an attacker could leverage this flaw to cause a denial of service that extends beyond the single application, potentially disrupting dependent services and causing what is known as scope change in attack outcomes.
From a technical perspective, the vulnerability enables unauthorized actors to trigger a hang or a frequently repeatable crash, effectively achieving complete denial of service against Oracle Secure Backup. This aligns with CWE-400, which describes uncontrolled resource consumption leading to exhaustion conditions such as memory leaks or infinite loops that prevent normal operation. The exploitability is notable because it does not require user interaction and can be executed by low privileged users who have already gained logon access to the host system. This lowers the barrier for entry significantly compared to vulnerabilities requiring high privileges or complex social engineering tactics. The ability to cause a complete denial of service means that backup operations are halted, which can prevent scheduled backups from completing and hinder disaster recovery capabilities during critical periods.
The operational impact of this vulnerability is severe due to its effect on availability, as indicated by the CVSS 3.1 Base Score of 6.5 with an Availability impact rating of High. In enterprise environments where Oracle Secure Backup manages large-scale data protection strategies, a prolonged outage can lead to significant business disruption. If backup jobs fail or are delayed, organizations may face extended recovery time objectives in the event of ransomware attacks, hardware failures, or accidental data deletion. Furthermore, because the vulnerability allows for repeated crashes, an attacker could perform a sustained denial-of-service attack that requires manual intervention by system administrators to restore service, thereby increasing operational costs and downtime. The potential scope change implies that while Oracle Secure Backup is the direct target, the collateral damage may affect other products or services relying on its availability, amplifying the overall risk profile for the organization.
Mitigation strategies should focus primarily on patching and access control hardening. Organizations running affected versions must apply the latest security patches provided by Oracle to address this specific flaw in the Device Management and Support component. Until patches are applied, it is critical to enforce strict least-privilege principles across all systems hosting Oracle Secure Backup. Administrators should review user accounts with low-level privileges on these hosts and ensure that only essential personnel have access. Additionally, implementing network segmentation can help isolate backup infrastructure from general corporate networks, limiting the attack surface available to potential intruders who might attempt to exploit this vulnerability after gaining initial foothold through other means. Monitoring tools should be configured to detect unusual patterns of service restarts or resource spikes indicative of a denial-of-service attempt targeting Oracle Secure Backup processes.
In terms of industry standards and frameworks, this vulnerability maps directly to CWE-400 for uncontrolled resource consumption leading to availability impact. It also relates to ATT&CK technique T1499, Endpoint Denial of Service, where an adversary disrupts access to an asset by exhausting resources or overwhelming the system capacity. Understanding these mappings helps in categorizing the risk within broader threat intelligence models and ensures that defensive measures are aligned with recognized best practices for mitigating availability-focused attacks. By addressing this vulnerability through timely patching and robust privilege management, organizations can maintain the integrity of their backup infrastructure and ensure business continuity even under adversarial conditions.
