Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NSummary
CVE-2024-53932 is a critical-severity Incorrect Permission Assignment for Critical Resource (CWE-732) vulnerability. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 28th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-53932 is a critical vulnerability in the Color Phone: Call Screen Theme Android application (package name com.remi.colorphone.callscreen.calltheme.callerscreen) through version 21.1.9. The issue stems from the com.remi.colorphone.callscreen.calltheme.callerscreen.dialer.DialerActivity component, which permits any other application—without needing special permissions—to silently initiate phone calls by sending a crafted intent. This flaw is linked to CWE-732 (Incorrect Permission Assignment for Critical Resource) and CWE-922 (Insecure Direct Object Reference).
The vulnerability carries a CVSS v3.1 base score of 9.1 (Critical), with attack vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating it is exploitable over the network with low complexity, no privileges, and no user interaction required. Any malicious application installed on the device can trigger it, allowing attackers to place arbitrary phone calls without the user's knowledge or consent, potentially enabling fraud, harassment, or premium-rate call scams that incur financial costs.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.
Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.
Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.
Associates security attributes with information to support proper access decisions on storage.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.
Directly protects data-at-rest confidentiality via encryption or access controls that prevent unauthorized reads.
Hardened baselines and configuration management explicitly include correct permission settings for critical resources.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.
Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.
Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.
Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.
Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.
By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
