CVE-2025-24904
HighSummary
libsignal-service-rs to wersja biblioteki libsignal-service-java napisana w języku Rust, która implementuje podstawową funkcjonalność komunikacji z serwerami Signal. Przed poprawką 82d70f6720e762898f34ae76b0894b0297d9b2f8, możliwe było wstrzykiwanie niezaszyfrowanych zawartości przez serwer lub złośliwego klienta, co mogło prowadzić do obejścia szyfrowania end-to-end oraz uwierzytelniania.
Risk Assessment
Podatność ta stwarza ryzyko dla integralności i poufności komunikacji, umożliwiając atakującym potencjalne przechwycenie danych użytkowników. Organizacje korzystające z tej biblioteki mogą być narażone na ataki, które mogą prowadzić do ujawnienia wrażliwych informacji.
Recommendation
Zaleca się aktualizację do wersji zawierającej poprawkę 82d70f6720e762898f34ae76b0894b0297d9b2f8, aby zabezpieczyć się przed tą podatnością. Należy również monitorować wszelkie zmiany w API związane z nowym polem `was_encrypted` w strukturze `Metadata`.

iperf3 3.20–3.21 (esnet/iperf) has a pre-auth heap buffer overflow in decrypt_rsa_message(): a 256-byte RSA buffer is BIO_read with the attacker-controlled ciphertext length (guard warns only), so an unauthenticated client overflows the heap via an oversized authtoken; fixed in 3.22

Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to. This could allow an attacker to associate a certificate with another user's account, affecting the confidentiality and integrity of that account's encrypted mail and, where certificate-based login is enabled, potentially permitting unauthorized access to the account.
- CVE-2026-102147Critical
A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.
Original NVD description (English source)
libsignal-service-rs is a Rust version of the libsignal-service-java library which implements the core functionality to communicate with Signal servers. Prior to commit 82d70f6720e762898f34ae76b0894b0297d9b2f8, plaintext content envelopes could be injected by a server or a malicious client, and may have been able to bypass the end-to-end encryption and authentication. The vulnerability is fixed per 82d70f6720e762898f34ae76b0894b0297d9b2f8. The `Metadata` struct contains an additional `was_encrypted` field, which breaks the API, but should be easily resolvable. No known workarounds are available.
