SHAREit through 4.0.6.177 does not check the full message length from the received packet header (which is used to allocate memory for the next set of data). This could lead to a system denial of service due to uncontrolled memory allocation. This is different from CVE-2019-14941.

SHAREit through 4.0.6.177 does not check the body length from the received packet header (which is used to allocate memory for the next set of data). This could lead to a system denial of service due to uncontrolled memory allocation.

The SHAREit application before 4.0.36 for Android allows a remote attacker (on the same network or joining public "open" Wi-Fi hotspots created by the application when file transfer is initiated) to bypass authentication by trying to fetch a non-existing page. When the non-existing page is requested, the application responds with a 200 status code and empty page, and adds the requesting client device into the list of recognized devices.

The SHAREit application before 4.0.42 for Android allows a remote attacker (on the same network or joining public "open" Wi-Fi hotspots created by the application when file transfer is initiated) to download arbitrary files from the device including contacts, photos, videos, sound clips, etc. The attacker must be authenticated as a "recognized device."

Cross-site scripting (XSS) vulnerability in Lenovo SHAREit before 3.5.98ww on Android before 4.4 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka "Universal XSS (UXSS)."

Lenovo SHAREit before 3.5.98ww on Android before 4.2 allows remote attackers to have unspecified impact via a crafted intent: URL, aka an "intent scheme URL attack."

The Wifi hotspot in Lenovo SHAREit before 3.5.48ww for Android, when configured to receive files, does not require a password, which makes it easier for remote attackers to obtain access by leveraging a position within the WLAN coverage area.

The Wifi hotspot in Lenovo SHAREit before 3.2.0 for Windows, when configured to receive files, has a hardcoded password of 12345678, which makes it easier for remote attackers to obtain access by leveraging a position within the WLAN coverage area.

The Wifi hotspot in Lenovo SHAREit before 3.2.0 for Windows allows remote attackers to obtain sensitive file names via a crafted file request to /list.

Lenovo SHAREit before 3.2.0 for Windows and SHAREit before 3.5.48ww for Android transfer files in cleartext, which allows remote attackers to (1) obtain sensitive information by sniffing the network or (2) conduct man-in-the-middle (MITM) attacks via unspecified vectors.
