InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

The version of Adobe InDesign installed on the remote Windows host is prior to 19.5.2, 20.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB25-01 advisory.

  - InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by an Integer Underflow (Wrap or     Wraparound) vulnerability that could result in arbitrary code execution in the context of the current     user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
    (CVE-2025-21158)

  - InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by an out-of-bounds write     vulnerability that could result in arbitrary code execution in the context of the current user.
    Exploitation of this issue requires user interaction in that a victim must open a malicious file.
    (CVE-2025-21121, CVE-2025-21157)

  - InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by a Heap-based Buffer Overflow     vulnerability that could result in arbitrary code execution in the context of the current user.
    Exploitation of this issue requires user interaction in that a victim must open a malicious file.
    (CVE-2025-21123)

  - InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by an out-of-bounds read vulnerability     that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass     mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open     a malicious file. (CVE-2025-21124)

  - InDesign Desktop versions ID20.0, ID19.5.1 and earlier are affected by a NULL Pointer Dereference     vulnerability that could result in an application denial-of-service. An attacker could exploit this     vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this     issue requires user interaction in that a victim must open a malicious file. (CVE-2025-21125)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Adobe InDesign installed on the remote macOS host is prior to 19.5.2, 20.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB25-01 advisory.
