However, new information led F5 to recategorize the flaw, indicating a risk of remote code execution, according to an update Wednesday.<br \/>\nThe new information shows that remote code execution can take place when BIG-IP APM access policy is configured on a virtual server, according to the company.<br \/>\nShadowserver Foundation on Wednesday released data showing more than 17,000 vulnerable IPs worldwide as of Tuesday.\u00a0<\/p>\n<p>When F5 originally released information listing the vulnerability as a denial-of-service issue, \u201cit didn\u2019t immediately signal urgency, and many system administrators likely prioritized it accordingly,\u201d watchTowr founder and CEO Benjamin Harris told Cybersecurity Dive.\u00a0<br \/>\nHarris said his researchers are seeing in-the-wild exploitation and warned that security teams would need to assess whether they\u2019ve already been impacted.\u00a0<br \/>\nThe Cybersecurity and Infrastructure Security Agency\u00a0added CVE-2025-53521 to its Known Exploited Vulnerabilities catalog on Friday. The agency gave Federal Civilian Executive Branch agencies a deadline of March 30 to remediate their systems, signaling the urgency of the situation.\u00a0<br \/>\nThe National Cyber Security Centre in the U.K. issued an advisory to alert security teams about the change, noting that BIG-IP APM is widely used in large enterprises.\u00a0<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Critical flaw in F5 BIG-IP faces wide exploitation risk https:\/\/www.cybersecuritydive.com\/news\/critical-flaw-in-f5-big-ip-faces-wide-exploitation-risk\/816475\/ Publish Date: 2026-04-02 11:41:00 Source&#8230;<\/p>\n","protected":false},"author":1,"featured_media":201605,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/imgproxy.divecdn.com\/YgoacB9MjHULnn1s6mMVICIEqOFVpBE_j7glMARWDbw\/g:ce\/rs:fit:770:435\/Z3M6Ly9kaXZlc2l0ZS1zdG9yYWdlL2RpdmVpbWFnZS9GNS1Ub3dlci1FeHRlcmlvci0wNS5qcGc=.webp","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[24,27],"class_list":["post-201604","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-cybersecurity","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/201604"}],"collection":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=201604"}],"version-history":[{"count":1,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/201604\/revisions"}],"predecessor-version":[{"id":201606,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/201604\/revisions\/201606"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/201605"}],"wp:attachment":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=201604"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=201604"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=201604"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
