Security Bulletin: Vulnerabilities in PHP may affect IBM Spectrum Sentinel Anomaly Scan Engine (CVE-2021-21703, CVE-2021-21708, CVE-2021-21707, CVE-2022-31629, CVE-2022-31628)

Security Bulletin


Summary

Vulnerabilities in PHP may affect IBM Spectrum Sentinel Anomaly Scan Engine. Vulnerabilities include: PHP allowing remote attacker to execute arbitrary code, obtain sensitive information, local authenticated attacker gain elevated privileges on the system, cross-site request forgery and denial of service.

Vulnerability Details

CVEID:   CVE-2022-31628
DESCRIPTION:   PHP is vulnerable to a denial of service, caused by a flaw in the phar uncompressor code. By using a specially-crafted gzip file, a local authenticated attacker could exploit this vulnerability to cause an infinite loop, and results in a denial of service condition.
CVSS Base score: 2.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237533 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L)

CVEID:   CVE-2022-31629
DESCRIPTION:   PHP is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to set a standard insecure cookie in the browser. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
CVSS Base score: 5.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237534 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N)

CVEID:   CVE-2021-21708
DESCRIPTION:   PHP could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free flaw when using filter functions with FILTER_VALIDATE_FLOAT filter and min/max limits. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause the application to crash.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/221046 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L)

CVEID:   CVE-2021-21703
DESCRIPTION:   PHP could allow a local authenticated attacker to gain elevated privileges on the system, caused by a flaw when running PHP FPM SAPI with the main FPM daemon process running as root. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges as root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/212017 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)

CVEID:   CVE-2021-21707
DESCRIPTION:   PHP could allow a remote attacker to obtain sensitive information, caused by a weakly configured XML parser. By using a specially-crafted filename containing URL-encoded NUL character, an attacker could exploit this vulnerability to read a different file than intended, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/214167 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
