  • CVE-2025-0159: Authentication Bypass in IBM FlashSystem (Storage Virtualize)

    Overview

    IBM has disclosed a critical vulnerability, CVE-2025-0159, affecting multiple versions of its FlashSystem product line through the IBM Storage Virtualize platform. This flaw is categorized under CWE-288: Authentication Bypass Using an Alternate Path or Channel and enables unauthenticated attackers to bypass authentication controls at the RPCAdapter endpoint.

    Vulnerability Details

    The issue lies in the handling of HTTP requests at the RPCAdapter endpoint. By sending a specially crafted HTTP request, a remote attacker can bypass authentication mechanisms entirely. This allows unauthorized access to sensitive administrative functions or data without requiring user credentials or prior access.

    The vulnerability impacts multiple versions from the 8.5.0.0 release through 8.7.2.1, including several patch levels across versions 8.5, 8.6, and 8.7. This wide range of affected versions underscores the urgency for enterprise customers using IBM FlashSystem to apply mitigations immediately.

    Technical Breakdown

    According to IBM and CVSS v3.1, the vulnerability is rated as Critical with a base score of 9.1. The CVSS vector is:

    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

    Key characteristics:

    • Attack Vector: Network
    • Attack Complexity: Low
    • Privileges Required: None
    • User Interaction: None
    • Confidentiality Impact: High
    • Integrity Impact: High
    • Availability Impact: None

    Impacted Products

    The vulnerability affects the following IBM Storage Virtualize versions:

    • 8.5.0.0 – 8.5.0.13
    • 8.5.1.0
    • 8.5.2.0 – 8.5.2.3
    • 8.5.3.0 – 8.5.3.1
    • 8.5.4.0
    • 8.6.0.0 – 8.6.0.5
    • 8.6.1.0
    • 8.6.2.0 – 8.6.2.1
    • 8.6.3.0
    • 8.7.0.0 – 8.7.0.2
    • 8.7.1.0
    • 8.7.2.0 – 8.7.2.1

    Mitigation and Recommendations

    • IBM strongly recommends upgrading to the latest version of IBM Storage Virtualize that addresses this vulnerability.
    • Restrict network access to affected systems and RPCAdapter endpoints wherever possible.
    • Monitor for unauthorized access attempts or suspicious RPC traffic.

    Conclusion

    CVE-2025-0159 represents a serious security risk for enterprises using IBM FlashSystem solutions. Its network-based, unauthenticated nature means attackers can remotely compromise systems without prior access. Prompt action is essential to protect sensitive storage infrastructure from exploitation.

  • CVE-2025-0070: Critical Improper Authentication in SAP NetWeaver ABAP Server

    Overview

    On January 14, 2025, SAP published a critical vulnerability identified as CVE-2025-0070 affecting the SAP NetWeaver Application Server for ABAP and ABAP Platform. The flaw is categorized under CWE-287: Improper Authentication and allows authenticated attackers to escalate privileges due to insufficient authentication enforcement.

    Vulnerability Details

    The vulnerability exists in the authentication logic of the ABAP platform. An attacker with valid user credentials can exploit improper authentication checks to gain unauthorized access to system functionality. This allows the attacker to escalate privileges and potentially control critical components of the affected SAP environment.

    Successful exploitation leads to a high impact on system confidentiality, integrity, and availability. Given the scope change and low complexity, this vulnerability presents a significant risk in enterprise SAP environments.

    Technical Breakdown

    This vulnerability is rated as Critical with a CVSS v3.1 base score of 9.9. The CVSS vector is:

    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

    Key attributes include:

    • Attack Vector: Network
    • Attack Complexity: Low
    • Privileges Required: Low
    • User Interaction: None
    • Scope: Changed
    • Confidentiality, Integrity, Availability Impact: High

    Impacted Versions

    The following SAP kernel versions are affected:

    • KRNL64NUC 7.22
    • 7.22EXT
    • KRNL64UC 7.22
    • 7.53, 7.54, 7.77, 7.89, 7.93, 7.97
    • 8.04, 9.12, 9.13, 9.14
    • KERNEL 7.22

    Understanding CWE-287

    CWE-287 highlights scenarios where systems fail to properly authenticate users or validate their permissions before granting access. In the context of SAP, such a flaw can be especially dangerous given the critical role these systems play in business operations.

    Recommendations

    • Apply the latest security patches provided in SAP Note 3537476.
    • Audit user roles and authentication configurations across all affected systems.
    • Limit access to exposed services and interfaces wherever possible.
    • Monitor logs for signs of unauthorized access or privilege escalation attempts.

    Conclusion

    CVE-2025-0070 represents a severe authentication failure in core SAP components. Due to the high potential impact and ease of exploitation, organizations should treat remediation as a priority and ensure all safeguards are in place to protect sensitive enterprise environments.
