Summary
CVE-2024-10748 is a low-severity Use of Default Cryptographic Key (CWE-1394) vulnerability in Cosmote What\'S Up. Its CVSS base score is 2.0 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Cryptographic key establishment and management requires generating and provisioning unique keys rather than relying on manufacturer defaults.
Requiring the most restrictive configuration settings prohibits the use of known default cryptographic keys.
Authenticator management requires secure distribution and handling of credentials, structurally discouraging hard-coded values.
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.
Credential/key management practices eliminate default cryptographic keys for identities and services.
Strong authentication requirements implicitly disallow default keys but do not address key management itself.
Configuration management directly prohibits default keys via hardened baselines and change control.
PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.
PR.DS-01 addresses encryption and integrity of stored data but never touches credential or key management practices, so it neither prevents hard-coded credentials nor removes any of their risk.
