Short explanation
In Cisco ISE’s web‑based management interface, the lack of server‑side validation of Administrator permissions allows an authenticated remote attacker to send a crafted HTTP request and modify parts of the device configuration (S0, S1).
An insider with valid Administrator credentials could tamper with system settings, undermining service integrity and trust.
What should be done?
- Enforce strong Administrator password policies (S0, S1)
- Restrict network access to the management interface (S0, S1)
- Follow the vendor advisory when released and apply recommended steps (S0, S1)
- Consider multi‑factor authentication for Administrator accounts (S0, S1)
- Regularly review audit logs for suspicious changes (S0, S1)
Chain of evidence and sources
İstismar için geçerli Administrator kimlik bilgileri gerekir (S0, S1).
Başarılı bir istismar, özel bir HTTP isteğiyle dosya açıklama alanlarını değiştirebilir (S0, S1).
Bu zafiyet CVSS 3.1 temel skoru 4.3 ile Orta şiddette sınıflandırılmıştır (S0, S1).
