Vulnerabilidades

A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of…

When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a…

Open OnDemand is an open-source HPC portal. Prior to versions 3.1.15 and 4.0.7, noVNC interactive applications did not correctly rotate the password when TurboVNC was higher than version 3.1.2. The likelihood of exploitation is low as a user would need to share their link to an active desktop session and the other…

A flaw was found in the Open Virtual Network (OVN). Specially crafted UDP packets may bypass egress access control lists (ACLs) in OVN installations configured with a logical switch with DNS records set on it and if the same switch has any egress ACLs configured. This issue can lead to unauthorized access to virtual…

A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service.

A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and properly configured.

A flaw was found in ovn-kubernetes. This flaw allows a system administrator or privileged attacker to create an egress network policy that bypasses existing ingress policies of other pods in a cluster, allowing network traffic to access pods that should not be reachable. This issue results in information disclosure…

A vulnerability was found in OVN Kubernetes in versions up to and including 0.3.0 where the Egress Firewall does not reliably apply firewall rules when there is multiple DNS rules. It could lead to potentially lose of confidentiality, integrity or availability of a service.

TurboVNC server code contains stack buffer overflow vulnerability in commit prior to cea98166008301e614e0d36776bf9435a536136e. This could possibly result into remote code execution, since stack frame is not protected with stack canary. This attack appear to be exploitable via network connectivity. To exploit this…

An XSS vulnerability was discovered in noVNC before 0.6.2 in which the remote VNC server could inject arbitrary HTML into the noVNC web page via the messages propagated to the status field, such as the VNC server name.

noVNC before 0.5 does not set the secure flag for a cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The Dubrovnik Guided Walking Tours (aka com.mytoursapp.android.app351) application 1.3.2 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Multiple PHP remote file inclusion vulnerabilities in Insky CMS 006-0111, when register_globals is enabled, allow remote attackers to execute arbitrary PHP code via a URL in the ROOT parameter to (1) city.get/city.get.php, (2) city.get/index.php, (3) message2.send/message.send.php, (4) message.send/message.send.php,…

Vlad Titarenko ASP VT Auth 1.0 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download the database file and obtain usernames and passwords via a direct request for zHk8dEes3.txt.

Stack-based buffer overflow in the CLogger::WriteFormated function in echoware/Logger.cpp in EchoVNC Linux before 1.1.2 allows remote echoServers to execute arbitrary code via a large (1) group or (2) user list, aka a "very crowded echoServer" attack. NOTE: some of these details are obtained from third party…
