CVE Record

CVE-2021-39057: IBM Spectrum Protect Plus 10.1.0.0 through 10.1.8.x is vulnerable to server-side request forgery (SSRF).

IBM Spectrum Protect Plus 10.1.0.0 through 10.1.8.x is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks. IBM X-Force ID: 214616.

Security readout for executives and security teams

Plain-English summary

IBM Spectrum Protect Plus versions 10.1.0.0 through 10.1.8.x have an SSRF issue. An authenticated attacker could make the server send unauthorized internal requests, potentially helping map networks or support follow-on attacks. Public sources do not show CISA KEV listing or active exploitation evidence.

Executive priority

Treat this as a moderate-priority backup-platform hardening issue. It is not currently supported as actively exploited, but backup infrastructure is sensitive, and SSRF can help attackers expand visibility inside networks after gaining credentials.

Technical view

The vulnerability is authenticated SSRF in IBM Spectrum Protect Plus. CVSS 3.0 score is 4.2 with network attack vector, low privileges required, no user interaction, high complexity, and low confidentiality/integrity impact. IBM X-Force tracks it as ID 214616.

Likely exposure

Exposure is limited to organizations running IBM Spectrum Protect Plus 10.1.0.0 through 10.1.8.x. Risk is higher where authenticated users can access the affected service from less-trusted networks. The source bundle does not identify other affected IBM products.

Exploitation context

The provided sources support authenticated network exploitation but do not support active exploitation claims. The CVE is not marked KEV. The likely impact is internal request forgery that may support network enumeration or other chained attacks, not direct unauthenticated compromise.

Researcher notes

Do not assume unauthenticated reachability or confirmed exploitation from these sources. Validation should focus on version exposure, authentication boundaries, network placement, and whether IBM’s advisory remediation has been applied. Evidence is limited to CVE, IBM advisory, and IBM X-Force references.

Mitigation direction

  • Review IBM advisory node 6525346 for official remediation guidance.
  • Apply IBM-recommended updates or fixes for affected Spectrum Protect Plus versions.
  • Identify and prioritize systems running versions 10.1.0.0 through 10.1.8.x.
  • Restrict access to Spectrum Protect Plus to trusted administrative users and networks.
  • Monitor vendor guidance and X-Force entry 214616 for updated remediation details.

Validation and detection

  • Inventory deployed IBM Spectrum Protect Plus versions.
  • Confirm whether any instance is within 10.1.0.0 through 10.1.8.x.
  • Check whether access requires authenticated, trusted administrative paths.
  • Review logs for unusual server-originated requests to internal resources.
  • Document remediation status against the IBM advisory.
