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 XSS issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. When users upload temporary files, some specific file endings are not allowed, but it is possible to upload .html or .htm files containing an XSS payload. The resulting link can be sent to an administrator user.

An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. When a password reset request occurs, the server response leaks the existence of users. If one tries to reset a password of a non-existent user, an error message indicates that this user does not exist.

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.

SerenityOS Unspecified is affected by: Buffer Overflow. The impact is: obtain sensitive information (context-dependent). The component is: /Userland/Libraries/LibCrypto/ASN1/DER.h Crypto::der_decode_sequence() function. The attack vector is: Parsing RSA Key ASN.1.

SerenityOS fixed as of c9f25bca048443e317f1994ba9b106f2386688c3 contains a buffer overflow vulnerability in LibTextCode through opening a crafted file.

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.
