Exploitation Conditions

Exploitation requires all of the following: (1) Local access to the macOS endpoint - no remote exploitation path exists (AV:L). (2) High privileges on the part of the attacker (PR:H per CVSS 4.0) - note a conflict exists between this metric and the description's 'limited privilege' language; the exact required privilege level should be confirmed against the Broadcom advisory. (3) Active user interaction (UI:A) - an administrator or privileged user must actively invoke the CleanWipe Removal Tool, so exploitation is dependent on a removal workflow being in progress. (4) Specific attack preconditions must be present (AT:P) - the exact environmental or configuration prerequisites are not fully disclosed in available data and should be reviewed in the vendor advisory. Exploitation is NOT possible remotely, is NOT possible passively without user interaction, and is NOT applicable to platforms other than macOS based on available tags.

Impact

The CVSS 4.0 base score of 5.4 (Medium) reflects meaningful mitigating factors in the attack vector. AV:L confirms exploitation is restricted to local access only - there is no remote attack surface. AT:P (Attack Requirements: Present) indicates that specific environmental conditions or configurations must exist before exploitation is possible, reducing opportunistic risk. PR:H signals that the CVSS scoring authority assessed the attacker as requiring high-level privileges to initiate the exploit. There is a notable tension between the CVSS PR:H metric and the CVE description's language of 'attacker with limited privilege access' - this discrepancy should be verified with the Broadcom advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/37625, as it could indicate that 'limited privilege' refers to a Symantec application role rather than OS-level user privilege, or that the CVSS vector was scored conservatively. UI:A (Active User Interaction required) further constrains exploitation - an administrator or privileged user must actively trigger the CleanWipe tool for the attack window to exist. No EPSS score was provided, and this CVE does not appear in the CISA KEV catalog, suggesting no confirmed active exploitation in the wild. Real-world risk is moderate and primarily meaningful in environments where CleanWipe is actively used for SEP removal workflows on macOS fleets.

Exploit ScenarioDerived

A local attacker who has obtained some degree of privileged access on a macOS system - for example, via a compromised admin account or an application-level Symantec role - waits for or induces an administrator to launch the CleanWipe Removal Tool to uninstall Symantec Endpoint Protection. During the active, user-initiated removal session (satisfying the UI:A and AT:P requirements), the attacker leverages the tool's excessive process privileges (CWE-250) to redirect execution or manipulate the privileged context to gain full administrative control of the macOS system. No public proof-of-concept exploit code has been identified at time of analysis.

AnalysisAIv1 – Jun 10, 2026

Local privilege escalation in Broadcom's Symantec Endpoint Protection CleanWipe Removal Tool for macOS, versions prior to 16.0.0.65, allows a local attacker to gain administrative control of the affected system. The vulnerability is rooted in CWE-250 (Execution with Unnecessary Privileges), a class where a process operates with more permissions than its function requires, creating an elevation pathway. No public exploit code has been identified at time of analysis, and this CVE is not listed in CISA's Known Exploited Vulnerabilities catalog; however, the full confidentiality, integrity, and availability impact on the vulnerable component (VC:H/VI:H/VA:H) underscores the severity of a successful exploitation.

RemediationAI

The primary remediation is to upgrade Symantec Endpoint Protection CleanWipe Removal Tool to version 16.0.0.65 or later, as specified in the Broadcom security advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/37625. Organizations should obtain the updated tool from the Broadcom support portal and replace any locally cached or pre-staged copies of the CleanWipe installer. As a compensating control where immediate upgrade is not feasible, restrict use of CleanWipe to trusted, monitored administrator sessions and avoid running the tool in environments with potentially hostile local users. Additionally, enforce macOS endpoint controls (e.g., Endpoint Security Framework policies, MDM restrictions) to limit which user accounts can launch privileged removal utilities. These controls reduce the available exploitation window but do not eliminate the underlying vulnerability - patching to 16.0.0.65 remains the definitive fix.

Technical ContextAI · show details

CleanWipe is a standalone removal utility distributed by Broadcom under the Symantec Endpoint Protection product line, designed to forcibly uninstall Symantec security agents from macOS endpoints. The affected CPE is cpe:2.3:a:broadcom:symantec_endpoint_protection_cleanwipe_removal_tool:*:*:*:*:*:*:*:* for all versions prior to 16.0.0.65. CWE-250 (Execution with Unnecessary Privileges) indicates the tool runs with elevated OS privileges beyond what its core removal function requires, and that elevated execution context can be abused by a local attacker to redirect or hijack the privileged operation. This is a well-known antipattern in security software removers on macOS, where tools often require and obtain root-level access to fully uninstall kernel extensions or system-level agents. The CVSS 4.0 vector (AV:L/AT:P/PR:H/UI:A) further indicates that exploitation requires specific preconditions to be in place (AT:P = Attack Requirements: Present), active user interaction, and high privileges on the part of the initiating principal - pointing to a scenario such as abuse during an administrator-initiated removal session.
