Citrix ADC and Citrix/NetScaler Gateway before 13.0-82.41, 12.1-62.23, 11.1-65.20 and Citrix ADC 12.1-FIPS before 12.1-55.238 suffer from improper access control allowing SAML authentication hijack through a phishing attack to steal a valid user session. Note that Citrix ADC or Citrix Gateway must be configured as a SAML SP or a SAML IdP for this to be possible.

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious c…

In BIG-IP versions 15.0.0-15.1.0.3, 14.1.0-14.1.2.5, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, a Cross-Site Scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility.

When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g. redirecting to '/foo/' when the user requested '/foo') a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module.

A vulnerability in the system file permission handling of Cisco APIC could allow an authenticated, local attacker to overwrite critical system files, which could cause a DoS condition. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to a race condition with handling system files. An attacker could exploit this vulnerability by doing specific operations on the file system. A successful exploit could allow the attacker to overwrite system files, which could lead to the device being in an inconsistent state and cause a DoS condition.

A vulnerability in the implementation of the internal system processes of Cisco APIC could allow an authenticated, local attacker to access sensitive information on an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to insufficient masking of sensitive information that is displayed through system CLI commands. An attacker could exploit this vulnerability by using reconnaissance techniques at the device CLI. A successful exploit could allow the attacker to access sensitive information on an affected device that could be used for additional attacks.

A vulnerability in the CLI of Cisco APIC could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to insufficient validation of arguments that are passed to specific CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of root.

A vulnerability in the web UI of Cisco APIC could allow an authenticated, remote attacker to perform a stored XSS attack on an affected system. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to improper input validation in the web UI. An authenticated attacker could exploit this vulnerability by injecting malicious code into specific pages of the web UI. A successful exploit could allow the attacker to execute arbitrary script code in the context of the web UI or access sensitive, browser-based information.

IBM Cognos Controller 11.0.0 through 11.0.1 FP3 and IBM Controller 11.1.0 is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.
