Description

Analysis

AI-generated

Technical impact

Citrix Workspace app for Windows contains an out‑of‑bounds read flaw that allows an attacker to read memory located outside the intended buffer. This reading can expose content of the buffer or adjacent memory used by the application, potentially revealing confidential data. The flaw does not let an attacker execute code or alter the program state; it purely allows the disclosure of memory contents.

Affected Systems

Citrix Workspace app for Windows versions older than 2603.11 Current Release, older than 2507.1 LTSR CU3, and older than LTSR 2607 are affected by this issue.

Risk and Exploitability

The CVSS score of 4.8 indicates moderate severity. The EPSS score of less than 1 % and the absence from the CISA KEV catalog suggest that widespread exploitation is unlikely at this time. The likely attack vector is local; remote exploitation would require additional conditions that are not documented. The primary risk is accidental leakage of sensitive information if the application runs with elevated privileges or handles privileged data.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Citrix Workspace app for Windows to at least version 2603.11, or apply the corresponding LTSR update.
  • Apply the principle of least privilege to limit the application’s rights to the minimum necessary.
  • Implement network segmentation or firewall rules to isolate workstations that run the Workspace app from untrusted hosts.
