Common Weakness Enumeration (CWE)

CWE-284 - Improper Access Control

Common Attack Pattern Enumeration and Classification (CAPEC)

Embedding Scripts within Scripts
An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
Signature Spoofing by Key Theft
An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

(CVE-2015-7977) - An unspecified flaw exists in authenticated broadcast mode. A remote attacker can exploit this, via specially crafted packets, to cause a denial of service condition. (CVE-2015-7979) - A flaw exists in ntpq and ntpdc that allows a remote attacker to disclose sensitive information in timestamps. (CVE-2015-8139) - A flaw exists in the ntpq protocol that is triggered during the handling of an improper sequence of numbers. A man-in-the-middle attacker can exploit this to conduct a replay attack. (CVE-2015-8140) - A flaw exists in the ntpq client that is triggered when handling packets that cause a loop in the getresponse() function. A remote attacker can exploit this to cause an infinite loop, resulting in a denial of service condition. (CVE-2015-8158)

description	ntp was updated to version 4.2.8p6 to fix 12 security issues. Also yast2-ntp-client was updated to match some sntp syntax changes. (bsc#937837) These security issues were fixed : - CVE-2015-8158: Fixed potential infinite loop in ntpq (bsc#962966). - CVE-2015-8138: Zero Origin Timestamp Bypass (bsc#963002). - CVE-2015-7979: Off-path Denial of Service (DoS) attack on authenticated broadcast mode (bsc#962784). - CVE-2015-7978: Stack exhaustion in recursive traversal of restriction list (bsc#963000). - CVE-2015-7977: reslist NULL pointer dereference (bsc#962970). - CVE-2015-7976: ntpq saveconfig command allows dangerous characters in filenames (bsc#962802). - CVE-2015-7975: nextvar() missing length check (bsc#962988). - CVE-2015-7974: Skeleton Key: Missing key check allows impersonation between authenticated peers (bsc#962960). - CVE-2015-7973: Replay attack on authenticated broadcast mode (bsc#962995). - CVE-2015-8140: ntpq vulnerable to replay attacks (bsc#962994). - CVE-2015-8139: Origin Leak: ntpq and ntpdc, disclose origin (bsc#962997). - CVE-2015-5300: MITM attacker could have forced ntpd to make a step larger than the panic threshold (bsc#951629). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

description	http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7973 NTP could allow a remote attacker to launch a replay attack. An attacker could exploit this vulnerability using authenticated broadcast mode packets to conduct a replay attack and gain unauthorized access to the system. NTP is vulnerable to a denial of service, caused by a NULL pointer dereference. By sending a specially crafted ntpdc reslist command, an attacker could exploit this vulnerability to cause a segmentation fault. NTP could allow a remote attacker to bypass security restrictions. By sending specially crafted broadcast packets with bad authentication, an attacker could exploit this vulnerability to cause the target broadcast client to tear down the association with the broadcast server. NTP could allow a remote attacker to obtain sensitive information, caused by an origin leak in ntpq and ntpdc. An attacker could exploit this vulnerability to obtain sensitive information. NTP could allow a remote attacker to launch a replay attack. An attacker could exploit this vulnerability using ntpq to conduct a replay attack and gain unauthorized access to the system. NTP is vulnerable to a denial of service, caused by the improper processing of incoming packets by ntpq. By sending specially crafted data, an attacker could exploit this vulnerability to cause the application to enter into an infinite loop. This plugin has been deprecated due to manual logic changes and advisory issues. Use aix_ntp_v3_advisory6.nasl (plugin ID 92356) instead.

These non-security issues were fixed : - fate#320758 bsc#975981: Enable compile-time support for MS-SNTP (--enable-ntp-signd). This replaces the w32 patches in 4.2.4 that added the authreg directive. - bsc#962318: Call /usr/sbin/sntp with full path to synchronize in start-ntpd. When run as cron job, /usr/sbin/ is not in the path, which caused the synchronization to fail. - bsc#782060: Speedup ntpq. - bsc#916617: Add /var/db/ntp-kod. - bsc#956773: Add ntp-ENOBUFS.patch to limit a warning that might happen quite a lot on loaded systems. - bsc#951559,bsc#975496: Fix the TZ offset output of sntp during DST. - Add ntp-fork.patch and build with threads disabled to allow name resolution even when running chrooted. This update was imported from the SUSE:SLE-12-SP1:Update update project.
