An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization).

It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire).

As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). Affected applications do not properly handle log rotation. This could allow an unauthenticated remote attacker to cause a denial of service condition through resource exhaustion on the device.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). Affected applications do not properly separate the rights to edit device settings and to edit settings for communication relations. This could allow an authenticated attacker with the permission to manage devices to gain access to participant groups that the attacked does not belong to.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application allows authenticated, low privilege users with the 'Manage own remote connections' permission to retrieve details about other users and group memberships.

A vulnerability has been identified in SINEMA Remote Connect Client (All versions < V3.2 SP2). The affected application does not expire the user session on reboot without logout. This could allow an attacker to bypass Multi-Factor Authentication.

A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. The highest threat from this vulnerability is to confidentiality.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). An attacker in machine-in-the-middle could obtain plaintext secret values by observing length differences during a series of guesses in which a string in an HTTP request URL potentially matches an unknown string in an HTTP response body, aka a "BREACH" attack.

A vulnerability has been identified in SINEMA Remote Connect Client (All versions < V3.2 SP2). The affected application inserts sensitive information into a log file which is readable by all legitimate users of the underlying system. This could allow an authenticated attacker to compromise the confidentiality of other users' configuration data.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP2). The affected application does not properly handle user session establishment and invalidation. This could allow a remote attacker to circumvent the additional multi factor authentication for user session establishment.

Cross-site scripting (XSS) vulnerability in the integrated web server in Siemens SINEMA Remote Connect Server before 1.2 allows remote attackers to inject arbitrary web script or HTML via a crafted URL.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0 SP1). Some pages that should only be accessible by a privileged user can also be accessed by a non-privileged user. The security vulnerability could be exploited by an attacker with network access and valid credentials for the web interface. No user interaction is required. The vulnerability could allow an attacker to access information that he should not be able to read. The affected information does not include passwords. At the time of advisory publication no public exploitation of this security vulnerability was known.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0 SP1). An attacker with administrative privileges can obtain the hash of a connected device's password. The security vulnerability could be exploited by an attacker with network access to the SINEMA Remote Connect Server and administrative privileges. At the time of advisory publication no public exploitation of this security vulnerability was known.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0 SP1). Some parts of the web application are not protected against Cross Site Request Forgery (CSRF) attacks. The security vulnerability could be exploited by an attacker that is able to trigger requests of a logged-in user to the application. The vulnerability could allow switching the connectivity state of a user or a device. At the time of advisory publication no public exploitation of this security vulnerability was known.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). The system images for installation or update of the affected application contain unit test scripts with sensitive information. An attacker could gain information about testing architecture and also tamper with test configuration.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). The affected application consists of a web service that lacks proper access control for some of the endpoints. This could lead to low privileged users accessing privileged information.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). The affected application consists of a web service that lacks proper access control for some of the endpoints. This could lead to unauthorized access to limited information.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). An error message pop up window in the web interface of the affected application does not prevent injection of JavaScript code. This could allow attackers to perform reflected cross-site scripting (XSS) attacks.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.0 SP2). Affected application is missing general HTTP security headers in the web server configured on port 6220. This could aid attackers by making the servers more prone to clickjacking, channel downgrade attacks and other similar client-based attack vectors.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.0 SP2). Affected application is missing general HTTP security headers in the web server configured on port 443. This could aid attackers by making the servers more prone to clickjacking, channel downgrade attacks and other similar client-based attack vectors.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0). Affected products contain an open redirect vulnerability. An attacker could trick a valid authenticated user to the device into clicking a malicious link there by leading to phishing attacks.
