The remote Solaris system is missing necessary patches to address security updates :

  - Cross-site scripting (XSS) vulnerability in     scheduler/client.c in Common Unix Printing System (CUPS)     before 1.7.2 allows remote attackers to inject arbitrary     web script or HTML via the URL path, related to the     is_path_absolute function. (CVE-2014-2856)

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-674:02 advisory.

    Description :
    The Common UNIX Printing System provides a portable printing layer for     UNIX operating systems. It has been developed by Easy Software Products     to promote a standard printing solution for all UNIX vendors and users.
    CUPS provides the System V and Berkeley command-line interfaces.
    Security issues fixed with this release:
    CVE-2014-2856     Cross-site scripting (XSS) vulnerability in scheduler/client.c in Common Unix Printing System (CUPS)     before 1.7.2 allows remote attackers to inject arbitrary web script or HTML via the URL path, related to     the is_path_absolute function.
    CVE-2014-3537     The web interface in CUPS before 1.7.4 allows local users in the lp group to read arbitrary files via a     symlink attack on a file in /var/cache/cups/rss/.
    CVE-2014-5029     The web interface in CUPS 1.7.4 allows local users in the lp group to read arbitrary files via a symlink     attack on a file in /var/cache/cups/rss/ and language[0] set to null. NOTE: this vulnerability exists     because of an incomplete fix for CVE-2014-3537.
    CVE-2014-5030     CUPS before 2.0 allows local users to read arbitrary files via a symlink attack on (1) index.html, (2)     index.class, (3) index.pl, (4) index.php, (5) index.pyc, or (6) index.py.
    CVE-2014-5031     The web interface in CUPS before 2.0 does not check that files have world-readable permissions, which     allows remote attackers to obtains sensitive information via unspecified vectors.
    Fixed bugs:
    These updated cups packages also include several bug fixes.
    Please see changelog for more information.

Updated cups packages fix security vulnerabilities :

Cross-site scripting (XSS) vulnerability in scheduler/client.c in Common Unix Printing System (CUPS) before 1.7.2 allows remote attackers to inject arbitrary web script or HTML via the URL path, related to the is_path_absolute function (CVE-2014-2856).

In CUPS before 1.7.4, a local user with privileges of group=lp can write symbolic links in the rss directory and use that to gain '@SYSTEM' group privilege with cupsd (CVE-2014-3537).

It was discovered that the web interface in CUPS incorrectly validated permissions on rss files and directory index files. A local attacker could possibly use this issue to bypass file permissions and read arbitrary files, possibly leading to a privilege escalation (CVE-2014-5029, CVE-2014-5030, CVE-2014-5031).

A malformed file with an invalid page header and compressed raster data can trigger a buffer overflow in cupsRasterReadPixels (CVE-2014-9679).

According to the versions of the cups package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A cross-site scripting flaw was found in the cups web     templating engine. An attacker could use this flaw to     bypass the default configuration settings that bind the     CUPS scheduler to the 'localhost' or loopback     interface.(CVE-2015-1159)

  - It was discovered that CUPS allowed certain users to     create symbolic links in certain directories under     /var/cache/cups/. A local user with the 'lp' group     privileges could use this flaw to read the contents of     arbitrary files on the system or, potentially, escalate     their privileges on the system.(CVE-2014-5031)

  - A string reference count bug was found in cupsd,     causing premature freeing of string objects. An     attacker could submit a malicious print job that     exploits this flaw to dismantle ACLs protecting     privileged operations, allowing a replacement     configuration file to be uploaded, which in turn     allowed the attacker to run arbitrary code on the CUPS     server.(CVE-2015-1158)

  - A cross-site scripting (XSS) flaw was found in the CUPS     web interface. An attacker could use this flaw to     perform a cross-site scripting attack against users of     the CUPS web interface.(CVE-2014-2856)

  - A localhost.localdomain whitelist entry in valid_host()     in scheduler/client.c in CUPS before 2.2.2 allows     remote attackers to execute arbitrary IPP commands by     sending POST requests to the CUPS daemon in conjunction     with DNS rebinding. The localhost.localdomain name is     often resolved via a DNS server (neither the OS nor the     web browser is responsible for ensuring that     localhost.localdomain is 127.0.0.1).(CVE-2017-18190)

  - It was discovered that CUPS allowed certain users to     create symbolic links in certain directories under     /var/cache/cups/. A local user with the 'lp' group     privileges could use this flaw to read the contents of     arbitrary files on the system or, potentially, escalate     their privileges on the system.(CVE-2014-5030)

  - It was discovered that CUPS allowed certain users to     create symbolic links in certain directories under     /var/cache/cups/. A local user with the 'lp' group     privileges could use this flaw to read the contents of     arbitrary files on the system or, potentially, escalate     their privileges on the system.(CVE-2014-3537)

  - An integer overflow flaw, leading to a heap-based     buffer overflow, was found in the way CUPS handled     compressed raster image files. An attacker could create     a specially crafted image file that, when passed via     the CUPS Raster filter, could cause the CUPS filter to     crash.(CVE-2014-9679)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Alex Korobkin discovered that the CUPS web interface incorrectly protected against cross-site scripting (XSS) attacks. If an authenticated user were tricked into visiting a malicious website while logged into CUPS, a remote attacker could modify the CUPS configuration and possibly steal confidential data.
