A vulnerability, which was classified as critical, was found in LibEtPan up to 1.9.4. Affected is an unknown functionality of the component STARTTLS Buffer Handler. The manipulation as part of a Response leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."
The weakness was released 07/27/2020. This vulnerability is traded as CVE-2020-15953 since 07/27/2020. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1055 by the MITRE ATT&CK project.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
