Vulnerabilities

Serenity before 6.8.0 allows XSS via an email link because LoginPage.tsx permits return URLs that do not begin with a / character.

An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. Password reset links are sent by email. A link contains a token that is used to reset the password. This token remains valid even after the password reset and can be used a second time to change the password of the corresponding user. The token expires only 3 hours after issuance and is sent as a query parameter when resetting. An attacker with access to the browser history can thus use the token again to change the password in order to take over the account.

A vulnerability was found in SerenityOS. It has been rated as critical. Affected by this issue is the function initialize_typed_array_from_array_buffer in the library Userland/Libraries/LibJS/Runtime/TypedArray.cpp. The manipulation leads to integer overflow. The exploit has been disclosed to the public and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The patch is identified as f6c6047e49f1517778f5565681fb64750b14bf60. It is recommended to apply a patch to fix this issue. VDB-222074 is the identifier assigned to this vulnerability.

SerenityOS before commit 3844e8569689dd476064a0759d704bc64fb3ca2c contains a directory traversal vulnerability in tar/unzip that may lead to command execution or privilege escalation.

SerenityOS 2021-03-27 contains a buffer overflow vulnerability in the EndOfCentralDirectory::read() function.

Kernel/VM/MemoryManager.cpp in SerenityOS before 2019-12-30 does not reject syscalls with pointers into the kernel-only virtual address space, which allows local users to gain privileges by overwriting a return address that was found on the kernel stack.
