CVE-2025-52572
CriticalSummary
Hikka, użytkownik bota Telegram, ma podatność, która dotyczy wszystkich użytkowników we wszystkich wersjach. Istnieją dwa scenariusze: brak uwierzytelnionej sesji w interfejsie webowym, co pozwala atakującemu na zdalne wykonanie kodu (RCE), oraz uwierzytelniona sesja, gdzie użytkownicy mogą przypadkowo zezwolić atakującemu na dostęp do swoich kont Telegram.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla bezpieczeństwa użytkowników, umożliwiając atakującym zdalne wykonanie kodu oraz dostęp do kont Telegram ofiar. Scenariusz z uwierzytelnioną sesją został już wykorzystany w praktyce.
Recommendation
Zaleca się używanie flagi `--no-web` i nie uruchamianie bota użytkownika bez niej. Po autoryzacji w interfejsie webowym, należy zamknąć port na serwerze oraz unikać klikania 'Zezwól' w pomocniczym bocie, chyba że jest to wyraźnie wymagane.

KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential; the JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, allowing the attacker to obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations.

A vulnerability in the Advanced Malware Protection (AMP) feature of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to write arbitrary files on the underlying operating system. It is due to improper handling of email attachments when the file reputation service is enabled; an attacker could send an email with a crafted attachment through an affected device, potentially allowing arbitrary file writes and command execution with root privileges.

A missing authentication vulnerability in Lantronix XPress-DR and XPress-DR-I (CoBos-family) firmware through 8.1.0.0 allows remote attackers to read and persistently overwrite device configuration by sending crafted frames to the unauthenticated UDP configuration protocol on port 30718. Attackers can send a type 0xF8 query to read live configuration data and a type 0xFD frame with exactly 0x78 body bytes to rewrite the device IP address and serial-channel forwarding records, causing changes to commit to EEPROM and persist across reboots. The XPress-DR product series reached end-of-life/end-of-support in February 2025.

Original NVD description (English source)
Hikka, a Telegram userbot, has vulnerability affects all users on all versions of Hikka. Two scenarios are possible. 1. Web interface does not have an authenticated session: attacker can use his own Telegram account to gain RCE to the server by authorizing in the dangling web interface. 2. Web interface does have an authenticated session: due to insufficient warning in the authentication message, users were tempted to click "Allow" in the "Allow web application ops" menu. This gave an attacker access not only to remote code execution, but also to Telegram accounts of owners. Scenario number 2 is known to have been exploited in the wild. No known patches are available, but some workarounds are available. Use `--no-web` flag and do not start userbot without it; after authorizing in the web interface, close the port on the server and/or start the userbot with `--no-web` flag; and do not click "Allow" in your helper bot unless it is your explicit action that needs to be allowed.
